IDK WHAT TO DO!!!

So I had a bf we were together about 2 months then he broke up with me cuz he felt “empty inside” then around September or October he said he missed me and we go back together. Then after that he completely cut me off from all social media and blocked me on everything. He someone contacted me a in January saying he wants to go to prom with me but just as friends. I said ok and we had planned to meet up to talk about things at the movies but that never happened. We went to the movies talked a lol bit then just made out the hold movie. After that we were back together ig and things were goin good until like 4 weeks ago he just completely cut me off again and I haven’t heard from him since. Now I don’t necessarily wanna get back with him I just want answers. I just wanna talk to find out why he hurt me so many times and never said sorry. I’ve texted his mom asking if he’s ok and she still never text me back so idk what to do anymore. Do I cut him off completely too, or do I still try and find out why he did all this?!???!? PLZ HELP I NEED ANSWERS😳😳😳
