Can anyone help me with my situation-ship?

I've been casually seeing this guy for about a month now. I've been drawn to him at least 2 months before, been almost magnetically attracted to him. We're hooking up casually cause he's in an open relationship. So i respect his boundaries and understand that. I'm just confused cause of how he behaves towards me sometimes, like this one time he called he over to his place and we hadn't seen each other in like 2 weeks and he greets me with a kiss. (very unlike him tbh) then the last time i was with him, he left a few hickies on my neck and he even wanted to cuddle for a bit, which is very unlike him as well. He's a very passionate man, knows how to please me and cares about my needs. i feel like im developing feelings for him but not to the extent that i am uncontrolled at least. but i wonder how he feels towards me. cause we're not too emotionally involved. i wonder if i should keep seeing him, cause honestly its very hard for me to do it.
