I feel for you.

And I don't think it has much to do with anything of being romantic, but the fact that you give him attention and affection, yet he doesn't seem to acknowledge it, which kinda feels at times like he doesn't acknowledge you. I have been there, and I remember it hurts a lot.

I don't know how long you two have been together, or how serious your relationship is, but I think the only thing that matters is you are going to accept this is who he is. Sounds like you want to be ok with this, but it also sounds like it's not the first time, and these things make relationships deteriorate over time.

I really hope you work things out, it sounds like you are a very sweet person.
