Is this self defense or worthy of an arrest?

My boyfriend stole my phone to go through it because he gets suspicions that I’m cheating (he found nothing) and I was asking for it back repeatedly but he wouldn’t. I grabbed his shirt and he pushed me, took me by the throat and slammed me against the door. I scratched his face and pulled his hair trying to get him off of me. His parents came downstairs and were saying if I called the cops I would be arrested too because I scratched his face, that I was part of it etc. I told her he choked me and she said “let me see your neck then? are there marks?” basically insinuating he has physical proof and I don’t. Its been a few hours, we’re separated now and I’m just wondering if that is actually true or not because I’m pretty sure it’s bullshit.
