Stuff happened

I don't even wanna post this but I don't know what else to do....

Basically like about 2 ish years ago I went to the sauna in the gym, and like I was maybe 17 at the time, and like there was this guy who I think was like 22, and basically I was talking to him and I thought I'd made a friend, but like, then he grabbed the inside of my thigh (you know where). And like my dad was nearby so he found out, and I spoke to the gym and they said he'd be banned but they never did, and my dad told me not to go to the police because they'd do nothing and "all itd look like is someone being uncomfortable with being gay" (I'm not even gay and tbh I didn't even plan on talking to the police because I don't trust them, but that's a separate issue). And like ages past but it's really bothering me, and it's caused problems, like I had a big falling out with my aunt over it (she doesn't know so to her and everyone else it just seems like me being a cunt), and also my dad as well, like multiple times he's said I led the guy on and it was my fault and blah blah blah, and my mum just backs him up and starts on me when I challenge him, and like the guy's been at the gym since multiple times, and the staff told ME to keep away from HIM, even after his friend threatened me both in the gym and in the street, and it's literally at the point where I had to switch to a gym that's like a 30 minute walk away whereas the one where it happened is only 10, because they won't do anything about it and every time I see the cunt I feel something between fuming and sick and about to collapse, what do I do 😭😭😭😭???
