<human>: Give me a shortened version of the text

I have been dating my (25m) boyfriend for about three months. Prior to this relationship I was in an unhealthy relationship where I was "gaslighted" constantly for close to two years. Being open and honest with this current boyfriend I spoke about my past and different events that have happened in my life that I am not to necessarily happy sharing. One related to this event was when I was passed out drunk at my friends house at the age of 17 and said friend began to violate me in my incoherent state. 

   So yesterday night I surprise visit him on his dinner break at work because we have not seen each other in a week or so. Not wanting to eat dinner we head up to an empty office to chat. We catch up and are having a great time and he tells me to lay on the carpeted floor. 
    
   So I did and we keep talking and looking at each other having a great time. Then he says he's feeling horny, but prior to this as he was making advances I told him "no, not today". Then he shuts off the light and as we keep talking he puts his hands in my pants. I tell him to "get his hand out" and he proceeds by pulling my pants down. As he starts to touch me I keep telling him enough. But my tone was not stern but you can tell I am flustered. He proceed to touch me and them he inserts his finger in my rear. This is when I enforce my tone and jump up. He apologizes, I pull my pants up and leave.

He has been calling and texting since apologizing. I understand his apology and I can rationalize his actions but I can not understand his lack of disrespect for me. We have a healthy sex life and I don't know how to handle this situation. I don't know if I am overreacting. I also feel a bit confused as we are in a relationship so the lines of violation can be blurred. I'm upset about the breaking of trust, respect and safety of our relationship rather than the actual act. Any advice will help me as I am utterly confused. Thank you
<bot>: visit boyfriend, tell him clearly I want nothing sexual for that day, he continues to make sexual advances and pulls down my pants. He touches me and then inserts fingers in my rear, confused on how to respond.
