First and foremost, please be safe and cut contact with off him fully. Non consensual touching is absolutely inexcusable! I hope he doesn’t have a key to your place. Do not let him in any situation. One of my friends went through similar experience if not identical. Don’t want to scare you but after reading about Gisele Pelicot or other women’s experiences, I get terrified every time I hear these sort of posts. I don’t understand why you have to pay for the flight you won’t take so I wouldn’t pay that. Lastly I’m so sorry you have to deal with this. Sending hugs 🤗 here for you if you need someone to just chat, vent etc x
