What would you do if you caught feelings

For someone you shouldn't have feelings for ??? Can't believe i'm posting about this on this site but i'm in over my head.

I have this friend, I wouldn't say we're close friends but we've gotten far enough to the point where we can laugh comfortably while insulting one another. He and I met through a group chat and have mutual friends, we regularly communicate via a server made for our group and never through dms, so I can't say i'm that special to him.

He and I so far up to this point have shared mostly stories about our romantic struggles, not so much other topics, which makes me feel a bit awkward. Though recently we've started talking about different subjects which, admittedly, made me a bit happy.

There's nothing wrong with falling for a friend, in fact it's one of if not my most favourited tropes out there. The thing is that i've been extremely involved in his love life, problematically so.

He talks to me about his other friends, which obviously has interest him, he denies it so profusely but anyone with eyes can see it. I make fun of him for it, I make fun of them for falling for him.

I've never seen him in a romantic light until just recently so I feel awfully guilty. He's only just broken up with his past boyfriend, and he's still very much so in love. Even if he denies that his friends have feelings for him I can still see that he knows that i'm right, and I know how burdened he is by the fact. I don't want to add on to that (Seriously what is up with this guy and making people fall in love with him?)

I don't know how to handle the situation now that i've unexpectedly developed a crush. Telling him to move on from his ex now feels like sabotage, making fun of his situation with his other friends now feels like i'm just being hypocritical. I know it myself that this can't ever be anything more and I don't plan on acting on it but the feeling remains heavy.

What the fuck do i do ????
