Is This sexuall assault ?😬

Harmony

So one time in 7th grade I was dating this guy and he asked if i wanted to go to the library( we were at school) with him I said sure. We went to a corner in the library and sat down i asked him why we were here and he said to have some fun I noticed that no one else was there and remembered that the library was closed that day , I was a little concerned but I didn't leave , he reached his arm around me and put his hand in my pants he held my but and then went around and started fingering me I tried to pull his arm out but he wouldn't let me I didn't want to scream cause I didn't want to get into trouble so I just let him do his thing. We never had sex but he fingered me without my permission , I never said no though I need help <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> please give me some advice 😬😔
