I have a huge crush on my best friend and think he might be gay

Sorry for the wall of text but this has been driving me crazy. This guy lived in my dorm suite last year and we became very good friends. The year before I accepted my sexuality and started messing around with guys. Anyways, we always make gay jokes and our friends joke that we're dating and would be a cute couple. A couple months a go something just clicked and ever since then I've wanted it to be more than a joke.Things that make me think he might be gay/bi:He played volleyball in high school (sorry, stereotypes are stereotypes for a reason)He's a 19 year old, good looking guy who's never had a girlfriendHe's laughs along with gay jokes until I joke about him actually being gay, then he either doesn't respond or abruptly changes the subjectHe is almost infatuated with his (straight w/ a girlfriend) roommate, who admittedly has a great body, always treating him like the pinnacle of fitness/appearance. I realize this can be common among straight guys looking up to others but it just seems excessive.In a conversation between me, him, and said roommate and girlfriend, he said there was this gay kid in his high school who knocked up a girl. I was skeptical so I said something along the lines of "Would you be able to get a boner with a guy?" He just looked awkwardly at the roommate like there was some kind of inside info there. I just laughed awkwardly and said I guess not??One time he said he was sore (assumably from lifting) and I joked "Too much butt sex?" He responded with the straightest face "you have no idea".We were recently talking about him pretending to be nice to a certain person. I said he was very good at acting like he liked this person and he just responded "Well, I'm very good at pretending" and paused like he was waiting for something. I know this is pretty weak evidence, it's just a gut thing.We were watching Netflix, I made a joke, we laugh and he says "I love you planetbucks". I say I love you too. This seems like it could just be best friends expressing their appreciation but IDK. This is more along the lines of him suspecting something of me, but in the past few weeks he's said to me something to the effect of "I don't judge people"I realize some of these are pretty circumstantial but in totality lead me to believe he has at least somewhat of an attraction to guys.He comes from a very strict Catholic (although very lovely) family, so I'm afraid that is part of what may be keeping him from coming out. Regardless of whether we would date or not, I just want him to be able to be himself. I've thought about bringing up the conversation and his reaction to the boner question to kind of breach the subject. But I don't want to a) push him if he's not ready to come out or b) anger him if I'm completely wrong. I would really appreciate other's perspective on this, thanks so much!
