I hate it when my boyfriend goes out without me

First things first, I have complete trust in my boyfriend and know he would never cheat on me. He doesn't go out a hell of a lot, and we spend most of our time together. I like his friends - I was friends with them myself before I even knew him. Yet it bothers me so much when he goes out and does stuff without me, whether it's going to the pub, out clubbing, or even if a group of his friends are hanging out over someone's house.

I sometimes think the reason is because 80% of his friends are heavy smokers, and he used to smoke quite heavily himself, plus they're quite big on smoking weed (my boyfriend also does it occasionally) and I've never been too fond of that. On the other hand though, if he went out with a different group of friends I'm fairly sure I'd feel the same.

I've never told him not to go out, and never would. In fact, I have the opportunity to go out with him 90% of the time because like I said, we have the same friends. I don't always do so because he needs to spend time without me sometimes, and just with friends. I can get a bit moody and distant with him when I know he's due to be going out, and I really piss myself of with that. As I said though, I'd never even think about 'disallowing' him to do anything.

I know it's dumb and paranoid and I need to get over it e.t.c. but I can't stop myself, and with fresher's coming up I'm really concerned about what that will do to me. I'll be going out for fresher's as well, but even when I'm out with my friends while he's out with his, I still spend a lot of the night thinking about him. I just can't figure out what it is that makes me hate it so much, and it's a **** feeling. Basically, I just want advice on how to not be such a paranoid *******.

Any advice would be very well appreciated, thank you!
