Oblivious Roommate: M/M romcom (Am I the Problem? Book 1)

Tl;dr: Am I the problem for trying to sabotage my gay roommate's relationship? I have my reasons!

I [20M] moved to a different college just so I can live with my best friend since high school [21M]. But it turns out that in the two years we lived apart, he's come out as gay, and he never told me! He also has a boyfriend, and I'm really not homophobic, but seeing them together bothers me. Other than that, we've reconnected like it's magic. Living with him is amazing, and everything would have been perfect if his ass of a boyfriend wasn't around. I don't think that guy is good enough for someone as funny, interesting, and cool as my friend.

How do I make him dump the stupid boyfriend?

Update: So I've been trying to break them up, and I'm starting to realize that, possibly-maybe, I'm the one who wants to date my roommate. Help! He's the hottest guy I've ever known and I keep screwing things up!
Also, is it gay to love smelling his sweaty T-shirt?

"Oblivious Roommate" is a best friends-to-lovers, gay-awakening steamy romcom filled with misunderstandings caused by an oblivious himbo who means well but has no clue.
While the books in the series share a setting each can be read as a standalone.
