CluelessAromantic

So I've essentially fallen head over heels for someone platonically or at least I think I have. Who knows honestly. Anyways, I want to bring up the topic of platonic relationships with him, but I haven't got a clue how especially since he's in a romantic relationship currently. I don't want to make things awkward considering my experiences are different than most people and often hard to relate to. For any context necessary, I am a grayaro ace trans guy, and he's a cishet guy (with a gf).
