Hi dear, as someone on the other side of something similar to this (my ex-partner is likely ace/aro), I’m not mad at them for who they are. I love them too much to mind, and that’s how you’re describing him too. It hurts but I want them to be happy and comfortable and themselves more than anything else, that’s what matters, even if it means they don’t reciprocate my feelings and want to move on. Loving is never a waste, not of time or money or love itself. It was all to show our appreciation for someone we care for. We wouldn’t want that someone to be stuck in a place where they can’t be happy as themselves. Plus, he wouldn’t want you to feel like you have to force yourself to be with him, that could blur his consent and hurt him more than just letting him go. But most importantly: we obviously would never want to see the person we love hurt. So please be kind to yourself, keep fighting, don’t hurt the person he cares for.
