Wrong or right

Am I in the wrong or do I have every right to be mad see when me and my boyfriend he likes to involve other people in our shit I feel like I’m dating not one but 2,000 other people there’s no privacy, no us. I can’t even talk to him without some wanting to put the two cents in it or hearing what we’re talking about when we do try to have an us day or date night his phone is always being blasted by people like today I wanted to have a private convo with his mom and his little brother asked me what is it that I need to talk about as of he’s the parent like it doesn’t involve you dude mind your business it’s always someone in our relationship I have like I’m not dating one but 2,000 I mean Ik when in marriage you marry the whole family but damn this is really driving me to the point of shaving my head or some shit and he literally said that I’d always come last to everything does that even seem right or fair at all plus I’m stuck I can’t leave I’ve tried it didn’t turn out so good
