Need help with my relationship?

I have a steady boyfriend and i love him to peices. I guess this isnt your normal relationship where I blame it on him. I am blaming myself for these problems. We get along wonderfully but I've had some very bad experiences with boyfriends in hte past. Ill put it this way... Ive been engaged twice. Both guys ended up being creeps. Ive never been ina relationship where I wasnt cheated on. But the last two fiances were good in other ways.

So my dilema is in trusting my current boyfriend. Hes like almost every other guy who looks at other women but he doesnt touch as far as i know. Hes very faithful but I still dont like when he gets aroused by other women. I think hes got pplenty of good to look at right here. And he likes to go out drinking without me. Hes cut it down to once a week but I still feel uncomfortable withit. IF i am there then I dont mind. But he barely ever gets a designated driver. He just drives drunk or rides with his buddies who are also drunk. I cant always go pick him up at 2am. Hes also a few years older and that worries me just cuz i want him to take care of his body so he can say around and live a healthy life with me. I hate to see something happen to him.

So I really think that this is mostly my personal feelings getting in hte way. Its not that i think about the other guys i have been with but its just a part of my personality to keep my gaurd up and keep from getting hurt. However I dont like that part of my personality. I wish i could just be easy going and not care. But it really gets to me. Does anyone have any suggestions on how to get myself to understand and change? Any help will be appreciated.Need help with my relationship?
