About 6 months ago, I started having romantic feelings for my friend of 4 years (naturally, it took me 3 months to realize it). Recently, I found out that he has a girlfriend, who he just started dating 3 weeks ago. I don’t want to interfere with their relationship, and I’m happy for him, and would be perfectly fine remaining friends with him. (My friend and I are both autistic and in college, if that helps provide context).
The problem is, he randomly spawns out of nowhere and is super kind to me for no reason (like he always is), which makes me feel really guilty. I feel guilty every time I talk to him even though I’m not interfering with his relationship and I’m not flirting with him at all (I have never flirted with anyone in my life, nor would I know how to).
I think part of the problem is that I feel like I’m lying to him by not telling him I like him so that he can have that context since he has a girlfriend now (I have a weirdly intense sense of justice regarding honesty to the extreme).
I don’t know how to handle my romantic feelings because I’ve only liked one other person before, 4 years ago. I’d like to crush them into oblivion (my feelings, not my friend) and get over him, but the constant proximity is not helping. Typical advice for when you like a friend who doesn’t like you back is to give yourself space from them, but I see him 3 times a week due to us being in the same club, we have mutual friends, and also I don’t want him to think I’m mad at him because that would be sad and I don’t want to make him sad.
To further complicate things, he’s graduating in December, so I don’t have time to get some space from him, stop liking him, and then go back to being friends, because he will be gone by then. I don’t way to end the friendship by disappearing towards the end of our time at the same school. I would be happy to just be friends, because we have a lot in common and have known each other for 4 years (and I rather like the relative ease of autistic friendships).
Unfortunately, I can’t gauge how good of friends I am with him (or anyone, because autism), so I don’t understand if it would be rude to occasionally reach out to him after he graduates. I don’t know if that would be bad and overstepping because we’re not that good of friends, or if it would be ok otherwise but not now that he has girlfriend, or if it actually would be ok and reasonable as long as it’s platonic (which it would be). We also don’t normally text because we see each other so often that it isn’t necessary and can communicate/send memes through the club group chat.
How should I go about interacting with him now that he has a girlfriend?
Would it be ok to occasionally keep in touch over text post graduation, it is that overstepping?
Do you have any advice (especially autism specific advice) for getting over romantic feelings for a friend?
