Search Results: mean anything to him

Hi guys, so I've had a crush on this one guy and I've been debating if I should dm him on insta wishing happy holidays? Will I come off as needy? Must say we talk and he tells me stuff even though he's the type of guy that doesn't tell anybody anything. FYI: Not too long ago I asked him why doesn't he add me on insta (I haven't requested anything just wanted to see his reaction) and he was in shock (he said noo way maybe that cause I'm barely there). Two hours later I sent him a request and he accepted it immediately (seems like he waited for me to do so) and sent me a follow request just as quickly. Does this mean anything?

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.
