Need some help with some one I met

I'm kinda new to hooking up (kinda)so I'm not sure how to go about it.I met some one recently for a hookup.He seemed nice the first time and there was some pain but I just chalked it up to not being accustomed to his size/haven't done it in a while.So I decided to see him a second time and the same thing happened and I noticed some things I really didn't like.He likes to drink ALOT, he even has a fridge in his room where he keeps knocking them back.I even noticed slight swerving on the road on the ride .His size is bigger then what im used too and even when I told him if he could go slower he does at first then he just starts going in hard.Saying things like "take it baby" or "you're all mine baby" even when I'm wincing in pain or saying no.My butt does tighten up but ONLY because hes jamming my prostate NOT because I actually enjoy so I guess that indicates to him that he should go even harder which means it ends up hurting even more.I'm a twink/nerdy type guy so I can't overpower him, he made that very clear when I tried to pull away but he just held me down kept going.He also says really weird things like he wants to marry me and that he wants me to move in with him and cook for him.Which freaked me out.Hes very clingy.Sending message after message as soon as I open the app.I gave him a second chance because I thought the discomfort from the first time was my nerves and size, so I thought it was all fault/in my head.I met him on grindr so I don't know what happens if I just block him.Does our whole conversion get deleted will he still be able to see my profile on the tap list?Or just deactivate the profile and try another app.I know it may seem weird to do this for just one bad hookup but I just have a very meek personality.
