Friends with benefits can a girl get a guide book here?

So I think I have a friends with benefits? I don’t really know? I just need a man’s perspective or well anyones really. I met him through church. Well his mom who was at church then him. We all went out to eat. He payed for us. Was sweet and respectful. Gave me his number if I needed any help with anything to give him a call. Well we ended up texting to hook up, I work a lot don’t have much time for dating I’m in a new town. So I don’t know anyone. I’m single. He’s 6 years older than me has no kids. Last night afterwards he mentioned his ex who we go to church with and how she wanted a baby but he didn’t want one so she got knocked up by someone else and married him. He’s mentioned that she drinks a lot. And is mentally manipulative, like she could have really messed up his life after he everything he’s done to fix it from leaving prison. So he slowly opened up to me last night. But he just like I don’t know shut down on me? When he left. He hasn’t messaged me like he normally has. Again this is just the 2nd time we’ve hooked up. Am I overthinking or? He’s mentioned he wants more to life he wants to travel he wants to do more. I was under the impression friends with benefits only message to hook up and that’s it but his words say something else. Like if my car acts up he gets upset if I don’t call him.
