Jealousy :|

I boyfriend is best friends with this girl, and they talk heaps and tell secrets etc...
Well while I was dating him still she had a crush on him and on her msn said 'you make me smile everytime I see you' and all that... I'm kind of friends with her...

too.
She's had a boyfriend since but have just recently broken up.
My boyfriend told me she had liked him when she started to go out with someone else... Why didn't he tell me while she liked him? Did he like her?
And he used to like her (not while we were going out).
They're still best friends and all, but I can't help to be jealous :s am I overreacting???
Also they talk heaps more then we do (boyfriend and I).
Do boyfriends act differently around their friends than around their girlfriends??

Thank you so much if you can answer my questions... I'm so worried that I'll loose him ...

well when a girl breaks up with a guy she wants a fall back a friend that when she needs comfort she can depend on him well ufortunatley thats how you start developing feeling and if it hasnt happen already its going to happen get to close to fast when shed depressed or he is they will commit stpid acts so girl friends are not so good in a relatoinship your pretty dont take that unless your snot so serious then thats your call good luck and remember know your worth

look boo just be friends with the chick and talk to her the more she talks to you the less she talks to him boo easy fix for big prob babe
