Fwb/fuck buddy

This dude was mad confusing and sensitive when we were hooking up the first time. This past weekend we linked up and he wanted to cuddle (he wanted to be the little spoon oddly but whatever) and he kept asking if I was trying to cuff him (aka date him) and I told him not unless he showed signs of that first because I’m not gonna look dumb or get hurt. He never gave a clear answer on what he wanted. After we had sex I was gonna leave but he offered to let me sleep with him and he left me in his room alone the next morning because he didn’t wanna wake me up (I knew this was gonna happen because we discussed it the night before since he had work in the am). Now I txt him askin his feelings and he says how he wants to be close, have sex when able, and get to know each other. Is he acting weird because he’s scared? What does this mean? What do I do?

P.s. he looks me in the eyes during sex, tells me how beautiful I am, and constantly kisses me. He gets awkward and nervous around me
