My commitment phobic friends with benefits stopped sleeping with me, got into a temporary relationship and now suddenly misses me. I don't know how to feel?

My friends with benefits stopped sleeping with me at the start of this year because he reckoned he didn't want to hurt me but that he couldn't do feelings right now because the sex would always come first.

Within a month he'd gotten into a relationship with an international girl who was only in the country for 6 months. I stopped talking to him at this point because I felt betrayed by his dishonesty. He broke it off with the girlfriend after 2 months because he wanted to keep sleeping around.

Now he's suddenly messaging me wanting to talk, telling me he misses me. That he never wanted to hurt me and the reason he's taken so long to try and reconcile was because he felt so guilty over the shitty way he treated me. That I'm special and he never even liked the girlfriend he just thought he needed something. He says he just wants to be friends again.

Now I don't know what to do in this situation. I had just managed to stop caring about all of this and now he's forcing it all back to the surface again. The fact that we had to stop sleeping together didn't bother me but the fact that he could suddenly commit to a girl he barely knew when he didn't want to commit to me actually shook me hard. Of course his reappearance came with a nice ego boost but I feel like letting him back into my life is a bad decision however cutting him off forever seems a bit extreme for a friends with benefits relationship especially since he seems to genuinely want to reconcile. What would you do?
