Oh i just found what this is all about here:

This is all cause he probably got mixed signs and got in the shower with her when they went in a trip as friends. After she said it wasn't ok, he got out and resented her.
It sucks, but i'm not sure this can even be considered Sexual harassment. He didn't actually harass her or touched her from what i understand.
The street harrasment part is the only one that is not ok in my view, if true. But that is verbal abuse, not sexual harassment. Not sure it's even a crime unless it's on the workplace or something, but that is not ok.
Still, i dunno. This doesn't sound like a super unusual or harassment story. It's just how things happen sometimes. Sometimes people make mistakes. Love is complicated.
