I didn't say no but I didn't say yes either....

After a 3 year relationship I'm back in the dating world. This guy messaged me from high school, always thought of him as a sweet guy. We decided to meet up for dinner and movies. Dinner went alright but we got to the movies and everything started. 
He put his arm around me and started grabbing my ass I honestly didn't think nothing of it. He then tried to grab my boob but pushed his hand off. We decided to move to different seats because some other couple sat behind us and it felt awkward. (It was basically an empty theater room with only a few other people inside that's why it was awkward) we got up and went through the back through the hallways. As soon as we hit a spot where no one could see us he grabbed my waist and put me against the wall. We started making out and he began pulling up my shirt. I immediately felt uncomfortable and wrong but said nothing. He started caressing my boobs and kissing them. I still said nothing. He stopped and I kept walking trying to te to our seats but he grabbed me again from behind kissing my neck and rubbing himself all over my back. He grabbed my hand and put it on his dick and I didn't know what to do. He kept saying he was going to "make me feel good" I told I couldn't do it. We needed up going to the cars and he tries again. He kept telling me that I was thinking about it too much and needed to let go. He starts unbutting my shorts and I guess I gave in because I helped in a way. He goes in with his hand and as soon as he touches me I tell I couldn't do it. He tells me again I need to stop thinking about it. But I just kept saying I can't do it. 
I guess in a way I gave him a free pass when I helped him with my shorts. I still feel so vulnerable and hurt afterwards like he took something from me. I don't know what it was but I've never felt so broken and empty inside where I spent hours sobbing into my friends chest and having multiple anxiety/ panic attacks. I just feel so scared... 
Any words of encouragement or advise would be nice.😔
