Was it assault or am I being dramatic?

So I’m not sure if this is assault or am I just being dramatic so I thought I’d get some opinions it’s a pretty long story so please read........... this happened to me in November 2019 my recent ex invited me over his house to hang and chill while his parents weren’t home. I’m not naive I knew going there that we’d probably fool around. I came dressed pretty basic but comfy I had just a tshirt and joggers pants but I didn’t wear underwear............. long story short we end up in his room in his bed In the dark. (It may get a little tmi but hopefully someone is still reading) so we’re in his bed and he starts feeling up on me and realizes that I have no panties on under my joggers. That gets him excited I guess so now he’s trying to get my pants off and I’m pretty inexperienced in the whole sexual stuff so I’m kinda like reserved and like fighting it a little so he just puts his hand in my pants and starts touching my vagina and rubbing it. He try’s to finger me and I’m like squirming cause it hurts so I’m like stop and he stops for a while but try’s it again and this time I feel like he’s roughly doing it so I’m really like moving and telling him to stop but he continues to do it. And it hurts it’s like he’s rubbing sandpaper on my vagina so I manage to get up and like bout to walk out of there but he says he’s gonna stop. And I don’t know if it was cause I really craved just some attention I stayed. Because the whole time I just was like I wanted him to rub my back massage me and give me kisses but he never kissed me on the lips not one time during this whole thing anyway He starts kissing on my neck and touching my boobs and stuff then he like humps me with his clothes on then a few minutes past by he takes his pants off. And I don’t say anything cause I was kinda feeling it and I give him a hand job, and I guess he thought that was the green light because he try’s to take my pants off again and I fight it and he try’s to finger me again but once again he’s not doing something right because it hurts and I’m like stop so he stops but takes his dick and starts rubbing it on my vagina and I’m moving away because I didn’t plan on having sex with him. Then he try’s to stick it in and I say stop so I get away and pull my pants up and I’m like I really need to leave like I got up and was trying to leave his room but he pulls me back in there. At that same moment he gets a phone call from a friend of both of ours and he answers. He used this opportunity while he’s talking to her to try to finger me again knowing I won’t scream stop because she’ll hear me and know it’s me there. I finally finally get away and manage to get downstairs to leave and he like walks me out but slams the door behind me so I don’t know how I feel or if I was being a tease and that’s why he did that or am I being dramatic. I told me best friend and she didn’t really have much to say but she said I should talk to somebody so I’m asking y’all opinions so be honest was I being a tease in all this or was he in the wrong? And sorry I know this story is long and probably all over the place it’s just hard to put the situation exactly in words.
