Not allowed to go out!

We have been together a year, during which my SO has had lads weekends away, loads of nights out where as I've NEVER been out without him not even to a friends house. So this weekend I asked and he straight up told me no I'm not going. We live near a party capital and he doesn't want me to get hurt. He said he can't trust me to go anywhere else because he knows I'll end up at this party place because that's what I'm like (which is true). But he has literally said no you're not going ever. Where as I have told him everytine that I'd rather he didn't and that I feel left out. I have barely any friends because they all like him and have tried to get in the way of our relationship. I'm stuck in the Josue all the time and have no life outside our relationship. I know it will eventually make me miserable. I am an adult and should be allowed to do as I please, not give up everything for him when he doesn't do the same. How do I get him to come around and understand? I'm not letting him do this. It's controlling and unfair. But how do I get him to give in? I deserve time away just like he does. We can't live our whole lives this way so somethings got to give. Someone please give me advice other than giving up on the relationship over one little thing.  It was hard enough when I couldn't go out because I didn't have friends, but to know that even when I get the opportunity I'm told no is rediculous. How do I say 'I'm going out wether you like it or not' without coming across as a stroppy child trying to rebel.
