Fwb advice

So it’s my first time having a fwb. So I’m new to this whole thing. I don’t have feelings for him but if he fell for me he’s definitely someone I could be into. He’s really sweet though, in ways that I wouldn’t expect a fwb to be. And there’s times he just wants me over to cuddle and not do anything else. We are both healing from previous relationships which is why it’s just a fwb. Am I dumb to think this could potentially go somewhere? If it doesn’t I’m fine but I just don’t know if this is common fwb behavior or not.
