Is he bluffing?

Hi everyone, I have an ex situation that needs sorting out. I got out of a toxic relationship 4 months ago, we were in love but neither of us were ready, especially me. During those 4 months of being broken up, we were talking on and off and I was actually doing a great job of letting him go. Around the time self isolation began, I decided to completely cut him off because I wanted to remove exes from my life since I don’t think it’s healthy. I blocked him for about 2 weeks and then unblocked him for whatever reason, honestly I didn’t think he would even reach out to me. He ended up texting me shortly after I unblocked him and we started talking, then we met and hooked up. After hooking up he began texting me first and I thought things would head in the right direction. Truthfully, I still have feelings for him and I thought he might change his mind about us.
We got in an argument over our feelings and he told me he still cares about me but doesn’t feel the same romantically. I truly think he is lying because he has no reason to text me certain things but he still does, all of my friends see it as him finding excuses to still talk to me. For example, he texted me a few days ago to ask my opinion on something when he could have asked anyone else. I mean, I believe if he truly did not care and was over me then he wouldn’t talk to me at all, right? He has a lot of friends and I know he talks to other girls so I don’t really see why he wants to keep me around, especially since he knows I still have feelings for him.
