What happens on guys' nights out?

Anonymous
My boyfriend and I have been on sort of a rough patch and said he needs space. He said he wants to start going out with his buddies (most of them single) more often. I trust that he won't cheat, but I feel uncomfortable and uneasy about him going out without me (what happens if he meets someone better? what happens if he realizes he wants to be single? what happens if he starts checking out other women and feels dissatisfied with me?).

I don't really like going out, since I have no close friends here since I started college 3 years ago. And also because he doesn't trust me (he hates my past, and before I met him I used to go out a lot and hook up with random guys, no sex though only making out). But anyway he has trust issues because he's been cheated on more than once, so I avoid trouble by not going out. But I kind of resent him having a lot of fun with the guys while I stay alone at home, with no one to be with. As I said, no close friends.

So what do guys do? How important are "chicks" on your nights out (as in, is it necessary to go to a strip club? or a regular club where there are hot single chicks? or is it unimportant and you can have a good night out without ogling being necessary?).

Thanks.

I know this is a huge insecurity issue on my part, but I don't like him checking out other women. I'm not really attractive to begin with (nothing I can help, short of surgery) so I just hate the fact that he wants to go out to see all these hot women.
