Jealousy , possessive and like being passive ?

You need to be careful because it sounds like you are thinking in a very obsessive way. It doesn't sound dangerous right now but I could see things getting worse in the future. It isn't weird to look for attention from peers and friends so don't think that you are the only person that feels that way. I am not going to speculate as to what in your upbringing has left you feeling this way because there are many possibilities and I am not a trained psychologist. Wishing to make your friend feel guilty for having other friends and talking to them is a big warning flag that you need to address. If you keep having theses feelings then you need to put some space between you and this girl until you can get a grip on your emotions. Then, you need to focus on why you feel that you need someone else to define your own self worth. Love yourself and believe in youself so that you can try to fight these co-dependency issues. You might have an addictive personality too so be aware of this possibility. When you need something/someone to cope or feel satisfied it is easy to transfer one addiction to another. Could be a girl, could be drugs or alcohol, heck it could be shopping. I am not saying that it would be easy to prevent these feelings, but if you are aware of your tendencies, you can think logically rather than letting your emotions take over. Have you considered talking to someone professional about this? I think you might be able to find out where these feeling originate from and then maybe you can start to resolve some of these obsessive emotions.
