Search Results: should we be friends

I was sexually assaulted in the waiting line in a grocery shop by an Ukrainian refugee, he grinded on me, at first I thought I was imagining things or that maybe it's normal in his country to stay very close in waiting line but when I felt his breathing growing very heavy on my neck / ear and felt him lean on me more and more I had no doubt anymore but did not fight back, I just moved of line.

Does it count as sexual assault since I did not say anything? Should I even bother to do anything? I do not want to be a mean person as I know Ukraine is at war and ptds and stuff and crazy but it did really made me uncomfortable too I was alone and he was with 3 others Ukrainian men (I'm guessing they were all friends or they were together during army service, my country train Ukrainian soldier and there's a military base near where I live). So if I say anything I have no one on my side and he have three people, also I feel bad for them I don't want them to be hurt or anything but what the guy did is not good.
