Re: Insecure = ruinin my relationship
I think you definitely need to lighten up a bit about him going out every week. I'm at uni and i'm out every other night at least!! He is still his own person and just because he has a gf doens't mean he should be limited with how many times he goes out. It would be different if he were not including you (if you lived near each other) or dogging plans with you for his friends. If he's not doing these things, he's actually not doing anything wrong. I think you need to focus more on yourself and your own social life... view your time away from him as healthy space where you can go out and see friends and do all the things you can't do when you're with him.
As for your insecurities, it is understandable you'd be jealous about other women at one stage or another. If you say he gets paranoid when you have guy friends, why don't you get some?? It will stop him winding you up about it... guaranteed.
Best of luck~
