Help i dont wanna loose him as a friend...?

Okay so yesterday this guy invited me over and said his friend was gonna be there and i didn't care cause i thought it was just a friendly thing to chill. Well my friend couldn't come and the only reason she was coming so he wouldn't try anything on me...Well she couldn't come so i decided to just go still. I was right down the street and he met me half way i had my drink in my hand and he was walking up to me so i said "i'm mad at you cause you made me walk here alone!" and he said "sorry" but than he put his hand around my waist and hugged me and try ed to slip his hand into the back of my pants and pulled up my shirt. On the way there he asked "can i have a hj?" and i kept saying "no" and he said sure as in he was joking...and than we got there and his friend wasn't any were to be found and i was told to go in his room i went in and he followed. Locking the door behind him and i said "no need to lock the door no ones gonna walk in on anything" and he walked up to me and looked at me and started to put his hand directly into my pants and trying to pull up my shirt after that he try ed to kiss me and i just wanted to be friends with him...and than i said no and slid my shirt back down and fixed my pants as i still had my drink sipping out of it he grabbed my waist and started sticking his hand in the front and i said no stop please! and he said are you gonna do anything and i said no and we sat there me just saying no i thought we were just gonna hangout? and him saying no ones gonna find out!? so i was like should i just leave and he said i guess. I left and felt guilty so i texted him saying im sorry and he said na bye and i just was like wow so i said is there anything i can do and he said yeah come back and blow me and i still said no so he said later that night send naked pics and i refussed and he hasn't talked to me since should i just forget about him? move on? Or what? should i just stop talk to him and just try to forget about him? He means alot to me still :/
