Breakup

I need to break things off with my boyfriend. he tends to very immature when it comes to things like this and makes me feel like a horrible person. I feel like I can’t do anything while I’m in a relationship with him. I can’t hangout with my friends, he doesn’t like my house so we don’t go over to my house, and whenever I’m gone on vacation or something I have to let him know everything or else he tells me I’m a bad person and not trying to get him involved. I feel as though he is getting very toxic and we are only 5 months into the relationship. I need help on where to start this conversation and how let him know!
