My best friend moved into my house a year ago and it's been pretty good for the most part. We're both single unmarried guys and he pretty much was at my house all the time anyway. We've always been super close and had a lot of sexual tension between us. A couple months ago a few things led to another and we ended up kissing and eventually having sex.

We've had sex several times since and he acts like my boyfriend but he doesn't want to officially be my boyfriend. We've had this weird dynamic where it's like this secret thing we pretend doesn't exist outside. I told him let's just make it official and be a couple but he doesn't want to. I'm not going to force him to be my boyfriend if he doesn't want to be but what bugs me is he clearly wants to be my boyfriend.

He gets super jealous and pissy with me whenever I go out with a girl or talk about the idea. He's super overprotective of me and cockblocks me if hes with me. So I'm like if you're going to do that then just be my boyfriend but he always avoids the subject. For some reason he doesn't want to be my boyfriend, at least not openly. He's either ashamed of his raging homolust for me or hes just ashamed of me, I honestly can't tell anymore. Either way it's quite frustrating because he won't let me date anyone else but he doesn't want to date me.

Why won't he just be my boyfriend?
