Was this sexual assault?

Im 14 when this happened and im 15 now, i was a party, i met this guy there and he was 16 and super drunk. He kept on kissing me and fingering me i told him to stop and tried to push him away but he was way taller than me and stronger so i couldnt. Ive never been fingered before that and im a virgin i dont know what to do. He made me give him a handjob and ive never done that before then either. I havent told anyone about this and im too scared to. Now he wants me to go on a date with him, he texted me saying sorry for being an asshole i was drunk and if i would go to the movies with him. Should i go? What do i do please help.
