Hook up

Hi there I am recently divorced and ended up hooking up with a guy I know through some friends. It was fun, and we planned another night to hang out. We chatted on and off until that happened, called each other a few times. He called me and had a long conversation that he really cared about me and wants to make sure we’re friends first and wants to see me doing well… etc, etc. Then we hung out and I slept over and we had a good time drinking and hooking up. He was pretty honest that he’s dealing with some things, as am I, and we weren’t really sure where things stood. But I made it clear I wasn’t looking for anything and if it happens again, great, if not that was ok too. Then after that happened I messaged a couple times (to just check in and friendly chat and/or hook up) and he kept leaving me on read and/or responding very sporadically.
Then I get a message that he’s sorry he’s been messaging me not as fast as he should be and that he just hasn’t has the mind for a lot of things. He means no disrespect. He hopes I’m doing well, etc. He had a chance in his day to message me so he figured he’d reach out but had to get back to work and have a good day. I responded thank you. Appreciate the honesty. Have a good day. Then he calls me tonight. I answered and he didn’t say anything so I hung up asking if it was a pocket dial? He called me again to which I didn’t answer and he said hey no sorry my phone didn’t connect to my car. So I just responded what’s up and he said “just wanted to say hi”.
Lol wtf? I truly don’t really care, but damn my curiosity is piqued. I just got out of a very toxic relationship and am mad this was my first rebound as it feels so much more complicated than it needed to be. Is he just an F boy, or does it sound like he’s got some issues he’s dealing with? Lol
