31F dealing with abusive guy 30M

Long story short. I have a stalker guy who’s delusional and thinks I’m in love with him even tho I have made it clear as day that I’m not interested in him.

Guess what he did, he tried to take revenge on me and made me life a living hell.

I also noticed that my phone was hacked and he was listening to my calls and reading my text like a toxic ex even tho we were never together. How do I know this ? My phone gets really hot and my battery drains fast and I can hear static when I’m on the call. ( you can google this to figure out if your phone is hacked)

When I confronted him, he tried to gaslight me and made me look crazy.

Now he’s forming a team and tried to take revenge on me for what ? For standing up for myself ? Because he didn’t want to take accountability ?

Why are guys like this because you rejected them ? Why are they so entitled ?
