Can people keep things casual?

I've been talking to a guy for a few weeks now. He has expressed a few times that he's not in a place in his life where he wants a girlfriend because he's constantly been in relationships for years. However, we talk all the time, get lunch together daily, sleep over at each other's places, and all relationship type things. I think he wants to be single but is a relationship type guy and can't help it. I like him a lot and he has said he likes me too but I'm worried I'll just end up liking him more and getting hurt. Should I just rip the bandaid off and end whatever we have? Or try to keep it casual and see where things go?
