But Sweepy, in a different post about this, you indicated you kind of responded to the kiss. Then you went back inside and cuddled with the guy on the couch, right? You said you were laying your head on his shoulder. If you respond to the kiss, and then cuddle with the guy, and then just don't respond or say anything when he comes in and starts kissing you and touching you again, I really cannot see that as a sexual assault or any form of abuse coming from the guy's side of this. The guy is not a mind reader to know that you changed your mind or felt horrible in between the kiss and cuddling and the time in the bathroom.
I do see how triggering this is for you though, and I really hope you can discuss it with your therapist.
