I've always considered him "straight"
But we've had this really weird intense "friendship".
I, admittedly, had a crush on him in college. And I made it known through my obsessive crazy behavior

But then I got over it and moved on.
He, however, has been weird with me.
Very touchy feely. He grinds on me. He talks about me sucking his dick.
He has this thing called "huggy time", where he comes and hugs me and then we fall onto the bed and cuddle for a while.
All of this changed when his "girlfriend" moved to L.A.
Now he's very tense, very strange.
He gets jealous, I think, of my other friends.
He's very bitter towards me. He has actually been quite cruel to me, and vindictive.
His girlfriend his fucking clueless. She once said, "you guys have a weird relationship"
But that's it.
Do you think I should address this? Should I talk to his gf? Should I just mind my business and leave? I'm moving out at the end of November. I don't see myself being friends with him after I leave. But I just can't believe that girl is with him and buying his hetero bullshit.

I almost want to tell her everything...but...iono
Should I just leave it? What would you do?
