I think you infatuated with a stereotypical musician. I'm willing to bet he's a chronic "one night stand" kinda guy (we can smell our own). And i'd also bet he treats most women the same way he treats you.
Why do i think this? Because it's the way i act when i want to get laid. The only difference, i make sure the chick knows i'm not out for a relationship.
Do what you want to do, but i wouldn't look into this as a possible relationship without asking him. REGARDLESS what your "feelings" tell you.
By the by, how old are you?
"We are all connected to each other biologically, to the earth chemically and to the rest of the universe atomically.
That’s kinda cool! That makes me smile and I actually feel quite large at the end of that.
It’s not that we are better than the universe, we are part of the universe. We are in the universe and the universe is in us."
