Confession

and he's so, just I don't know. I stated talking to him because I thought his wallpaper was kurt cobain and started raving about nirvana like a dumbass, and ended up hitting it off anyways.
I can never tell if he's joking or not, he's so confusing. Like he is always talking about how he want this guy to fuck him, would totally marry a guy, is definately going to a gay bar one day. but then says hes straight.(Keep in mind this dude is also the class clown) I'm not gonna question, it's not my decision to decide what his sexuality is. But at this point I feel like he's sending signals, he knows I'm lesbian and ask me a lot of questions, about the lgbtq+ community and all the lingo. And always hits on this one dude, actually they flirt with each other alot, I mean full on groping each other, sitting on each others laps, professing their love, kissed each other, They actually got married two days ago (I was their best woman) I wont go into the rest but like fuck. No one can tell if there just joking or actually dating each other.

And he's asks a lot of serious questions about lgbtq+, He even told me that he would love to date the guy he's doing all this with, but is pretty sure hes homophobic.
We joke around a lot, And people have said that anything that comes out of our mouths sounds sarcastic, even I cant tell. I don't want to acidentally out him, or go to bold assumptions. so like how should I deal with this? Im I reading in to much or should I just leave it? my brain is exploding.
