You know the answer or you wouldn't be asking the question
I’ve very quickly become close with a married friend in a troubled relationship. I’ve been responsible in how I’ve behaved, but I have feelings for him. He hasn’t made a move, and I don’t think he would, but our dynamic feels like if he weren’t married we would absolutely be moving toward being together already. So I’m trying to figure out: What are my obligations? I care deeply about our friendship and don’t want to ruin it or pull away from it.
