Was i assaulted?

Well to keep this short, i 22y was seeing this guy 28y, we agreed both on being exclusive to each other on the first time we saw each other, and i firmly stated that im side only and he agreed on that, we got along together, i can say we were in some kind of relationship but he referred to it as a companionship

Fast forward to this time, in his apartment, side note we only met in his appointment never went on an actual date or anything, anyway i was sick and told him beforehand that im not in the mood to do anything and he agreed and he asked me to come over and we can just talk and sleep in his arms

Anyway i got there, we were laying in bed and i started feeling sleepy, he started teasing me and getting his hands in my shorts, then he he asked me for a bj and told him im tired but i did it anyway

Next thing he wanted to top me, and immediately said no, he said it's okay, but then he asked again and again and against my better judgement, i should have left but i liked him a lot so, after a while i finally said yes and he tried fuckin me, he told me to get on all fours and rise my ass up, then he started, and i immediately felt discomfort and pain and i didn't like it at all, abt 5 min he slide it in me completely and i felt so much pain and told him to stop but he kept going, so i pushed him off me, he apologized a lot, and i was feeling awful and told him i should leave, so i get dressed and left and walked back home

Shortly after i found out he was on grindr and hooking up with others so i immediately blocked everywhere
