how can i stop this...???

You have very low self esteem. If your boyfriend doesn't give you any means to react this way then YES it's all in your head. You have probably been hurt,lied,cheated or deceived in the past. Well that's the past. You have to look ahead to the present/futur now. Just because others have deceived you doesn't mean that your present boyfriend will. You have to take a chance in life and open your heart. It's better to have Loved and Lost to have never had Loved at all. Have a little faith and trust in him. But if he does deceive you then hunt him down and shoot him. hahaha !

ok well I have the same fear and in the and the guy acually dumped me and now I can't figure out why. The main thing u need to remember is that he must like u some to begin with since ur dating so when u feel in doubt just remember he's with u now and thats not changing live for thwe moment and don't get jealous that will be sure to loose him if u need more help just e mail me

hey gurl well i know exactly how you feel! i feel the same way towards my bf. but i have this doubt in my mind that i am going to lose him too! the only advice i ahve is cherish what you have RIGHT now dont let some thought throw your whole relationship off...or even cause future problems for it! just enjoy being with him while you can and if something does happen that you lose him know that it maybe just wasnt meant to be! whatever happens happens!

once it happens to u then ur going to be thinking about in every relationship that u get into. im doing that right now but my boyfriend is really good to me, so i really try not to worry if i lose him. all i can say is that just relax not even relationship that u have will be the same.

you are the only one that can stop this. you have to decide if your going to trust him or not. i have a saying that a man is only as faithful as his opportunities and I don't trust my husband but to a certain degree but heck what will be will be i refuse to be in the state of mind that your in anymore. I had to learn to just let it go and approach the situations as they come up!

Pray and ask god to remove it from you.
