I think my friends gf has a crush on me

My friend isn't really open about his relationship, but it is so obvious that they are dating. + things I've seen their emails before and they were sending hearts to each other, and planning dates and stuff, so pretty damn obvious.

But, since his gfs started hanging out with our friend group, she primarily is talking to me and him, but seems to be talking to me more? Whenever were walking to classes all together, he often falls behind or walks ahead because she is talking to only me about something like politics, or something along those lines, as, my bsf may be funny, but he knows jack shit about any politics to a concerning point, + just isn't that intelligent I guess you could say? Which, his gf definitely is, she talks about politics quite a bit and similar topics.

Ive made a couple jokes to her too, and at one point she put her hand on my shoulder while laughing? She overall just seems to interact with me more than him, and I've noticed she also just isn't really finding him that funny. This is indeed a girl that I've thought I wouldn't mind being with, (being aromantic I don't really get serious crushes, just people that I consider dateable and not I guess), but I don't want to make my friend sad or anything.

But, another thing is, I'm pretty sure my friend likes me too? Were both guys, but both bisexual or just unlabeled. We recently had a school camp, and he was constantly leaning on my shoulder and holding my hand on bus rides, and, when we were on a walk on said camp, he was once again holding my hand. And, he started saying I love you, seemingly jokingly, but we had a full hour long talk about him trying to tell me something, which, was pretty obviously that he liked me, as he had said various things like, after I sent a gif of some girl, he said "smash...do you wanna know something? i wasn't talking about the girl", and another thing, he said . .... ..., same amount of words and letters as "i like you" and he made multiple jokes about it later after I figured out what he meant with that, but still denied actually meaning it. And, just for context, we actually have dated before, but it was only for a bit, as I chickened out of the relationship pretty much, being incredibly indecisive. He still constantly makes jokes about liking me or just inappropriate jokes way more around me than anything else, which confuse me even more

All of this is so complicated dude, I genuinely don't know what any of this means, and I'm pretty sure 2 of my other friends like me too but I'm not gonna go into that because its even more complicated, I must sound so self centered with saying so many people have crushes on me but I'm completely serious about all this
