Your ex wasn't that jealous... And the ex before the last ex used to suffocate you with her motherly care. Your present girlfriend, on the other hand, would be perfect if... You can go on and on all night with your comparisons, but this won't help you understand what's up with your love life.

The truth is every person has his (or her) loving style, you like it or not.
1. Jealous love
Password: "You don't love me!" or "Do you really love me?"
Typical behavior: No person is jealous without a reason. So, it's either one you offered her (a clear proof of infidelity), or one that is deeply located inside her. If you cheated on her once, she'll never forget even if she pretends she forgave you. No wonder she insists on being informed on your daily schedule, minute by minute. The pathological jealousy is even harder to bear for both parts. Your beloved one is insecure, frustrated without any particular reason coming from you. She doesn't feel at ease with her own person and she fears you'll notice her faults someday. The good part of this is that she has a very good opinion about you: you are a better person, more beautiful, funnier, smarter, and the list could go on. Deep inside her she wonders why you felt attracted by her in the first place and considers it's only natural that you change your mind every time you encounter a "better option".
Take it or leave it: My friend, if you have been unfaithful and she discovered your infidelities, you have no other choice than to be her slave for an unlimited period of time. Sorry, your mistake! As for the "pathological jealous girl", you have three options: a) you leave her (even if she threatens with suicide); b) you live with her and do nothing (in which case your life will be pure hell); c) you try to make her feel valuable and cure her jealousy (you know, with sweet nothings women like "Your the most beautiful women I've ever fallen in love with", "Ho come you're so smart?", etc.).
2. Demanding love
Password: "You want me, show it to me!"
Typical behavior: It's probably your fault, but only if you started this relationship by bribing her. She has never really loved or especially liked you, but what the hell, she can't say "no" to the royal treatment she gets! She might not realize that the real object of attraction for her is not your person, but the social status that comes with you. Most parents in different cultures educate their girls that way (with the impression that man must supply for his woman), so blame them! The girl with a demanding love style is in a constant need and her "negotiating terms" oscillate between material demands (shoes, cars, perfumes, etc.) and emotional ones (a quick marriage certificate, your almost permanent loving presence).
Take it or leave it: If it's you who taught her ask for things, you should try to change the situation, because this kind of relationship doesn't have a long life. Even if you fear she'll dump you! Eventually, she would anyway (when she really falls in love with someone else or when someone more generous crosses her way). There is, though, this slight chance that she love you and her demands are the result of a bad education. You can explain why her style is defective and if she doesn't leave you, your relationship will evolve for the better.
3. Generous love
Password: "Tell me anything you want and it's yours!"
Typical behavior: The exact opposite of the demanding love! The girl is used to buying things she likes and, surprise, you're one of them (especially if you are not even near as rich as her) ! For a while, you might enjoy such a relationship, but only until time will teach you a lesson: that nothing is for free. You tell her you don't love her anymore and try to dump her? She gives you a shiny new convertible! Your enthusiasm is in a scary decreasing state? Look, she has a Cartier watch for you! It's the only way she knows to handle situations, but don't despise her! She is not happy either. Behind this apparent authority, there is a very frustrated person (lives under the impression that she is not valuable enough to deserve a man attention).
Take it, or leave it: One thing is sure – she loves you. And if your reasons for being with her are sincere, help her get a better image of herself.
4. Expecting love
Password: "If you love me, I love you."
Typical behavior: You know, life near this girl could be funny if it weren't so sad! It's like being partner with an echo. Produce a sound and it will react. Say nothing and you're as good as alone! She can't just fall in love because she fears rejection. And the unsaid conclusion, once, was that she'd be more protected without investing too much feeling in a relationship. She gives rare proofs of affection, usually when you are open hearted too.
Take it, or leave it: Her way of loving must be the result of an ex unhappy relationship, in which she's been too deeply involved (either with a lover, or with her parents who were very cold people). In any case, there is a cure: show her unlimited love, discuss every misunderstanding to prevent it from becoming a crisis.
5. Oscillating love
Password: "May be I love you, maybe not..."
Typical behavior: Your sweetheart is the undecided kind, not only in love matters. Whereas her difficulty in choosing between two pairs of shoes does not affect you directly, her oscillating feelings touch you in the most unpleasant way. Today she feels very in love, tomorrow she thinks to pack her things and leave. Want the cruel truth? She isn't in love with you, but with the idea of love. That's why the slightest couple argument makes her question the relationship.
Take it or leave it: If you don't give her up, she will when she meets The One. You can be sure she's continually looking for him.
6. "One way" love
Password: "I love you for both of us."
Typical behavior: It's a very frequent declaration in many couples. But instead of being tempted to decide that the one who says it has a really big heart, try to understand what it really says: "I don't care what you really feel. I like you, and that should be enough for you." There's no trace of love here. It's only about possession. Also, someone who accepts living such a "love story" doesn't love his/her partner. Maybe it's fear, indifference, or anything else, but not love.
Take it or leave it: Definitely leave it!
7. Egoistic love
Password: "If I can't have you, no one will!"
Typical behavior: This "egoistic love" is very similar to the "one way" love. only more violent. Your woman tries to get to your heart by force. Her constant menaces show a dangerous psychic deviation.
Take it or leave it: Run and hide!
8. Pygmalion love
Password: "You need to change."
Typical behavior: Well, most of us (men or women) create a certain pattern for our future partner. This explains why we most frequently want our partner to change according to our pattern. So, your girlfriend begins by changing your dressing style, your haircut, your perfume, then redecorates your house, etc. The unacceptable part comes when she insists on changing your ideas and your friends.
Take it or leave it: Give it another chance, after explaining that you like yourself as you are and so should she. Anyway, you will both change because that's what living in a couple does.
9. Physical love
Password: "I just love your body."
Typical behavior: You don't remember when you two had a discussion, doesn't matter on what topic! You spend very much of your spare time together in bed, because there really aren't any other things to do considering common passions do not exist.
Take it or leave it: Keep her for sex, but search your love somewhere else!
10. Motherly love
Password: "Stop biting your nails!"
Typical behavior: Life near her is like childhood. She is a kind of mother substitute: washes for you, irons for you, even cooks for you, not to mention the public corrections ("No, don't throw that paper on the street!").
Take it or leave it: Guys usually search for someone to remind them of their mothers. You found her, now live with her!
