Does my ex want to get back together, or is he sending mixed signals?

Me and my ex broke up 3 months ago.. we recently have been sleeping together casually again.. last night he had told me he’s tried hanging out with other girls and even tried to sleep with someone but couldn’t even get hard and said it was because no one can measure/compare to me. He had been drinking. I’m not exactly sure what he expects me to do with that information.. especially since he hasn’t talked or made any effort outside of sleeping together of wanting to work on things or get back together. I’ve told him I cannot keep just sleeping with him casually and will need to move on a week ago. This isn’t the first time he’s made comments like that either tho. We didn’t break up due to anything bad.. we both were going through a bunch of major life events/changes and I guess he chose to leave instead. He had to rebuild his whole life after some losses/things happening and was under a lot of stress, but I was also dealing with the loss of my dad, plus other stuff and emotional.
I still love him, and really don’t want anybody but him. But I’m also prepared to move on if he’s just playing with my emotions.
