The question seems pretty straight-forward but I'm getting to that, I've looked this up earlier but the only thing I could find was the fact I could possibly be aromantic, but I don't think that's right. I've had romantic crushes before, especially on this one guy who I have become friends with. We have known each other for a year now and have recently started dating, this seemed like a dream to me but I realised after a few weeks I started not liking him as much and now I feel like we should just be friends. I don't know why but I just get tired of relationships, I can fantasize about them though. Why do I feel like this?

I don't know if you are or not honestly, but it's hard for reality to compete with fantasies and daydreams though. Is that fair to the guys you date? It is something to think about if this always happens when you date others.
