I think it is nice that you have a friend and a crush on him too.
I think it is a wonderful thing that you have someone, even just to talk to and be with.
Cancer can be treated, I don't know what type he has, but you being there with him, makes a world of difference I bet.
We all need and crave attention. I understand the part about being hurt again too. We always have our guard up, that's okay too.
Enjoy yourself, you deserve it.
Hugs, Nikko
