I have an ex, and he is extremely obsessive and controlling. It all started when he used me as a fuck buddy for a while when he was currently fucking everyone in our friend group. He got to me last and I fell for him. He broke up with his gf for me and we ran away from the group living on our own. Then, as soon as I got comfortable he had left me. Little did I know he was still with his ex, and he kept coming back and then leaving for months. His ex found me and started attacking me on the streets, thank the lord I had Vincent (My friend, now my current bf) there with me to protect me since I was a 19 year old thats 4'11 and very small. My ex didn't care and left again until he broke up with her. He came back and abused me for that summer which made my mental issues WORSE and I had to go to a mental hospital. He said he would wait but when he came back he left again. The last time he came back I lost feelings for him and rejected his offer to get back with him, plus I had a new boyfriend, Vincent. Ever since I've rejected him he's done everything he can to get to me. Make fake social media accounts, got his sister to talk to me, even his ex's that he knew I hated. Sometimes he even comes to our apartment (Since we go to the same college and he knows where I stay). Vincent is a little older and more stable than me so thankfully we can move soon. But this has really become creepy. He stalks me and Vincent sleeping and he's been in 6 fights with him. Fist fights. My ex has been put in the hospital by Vincent 4 times and still won't give up. He has to constantly protect me and it's starting to get scary. The police won't belive us and his sister and ex are only making it worse. Is there anything I can do to stop this other than moving?
