Basically he has always been very inappropriate towards me in a sexual way, because of this I cut him off from my life completely a few years ago. My sister decided to "bring him" back to my life" by bringing him to a party and not telling me he was coming, I was polite towards him but that was it... since this day he waits for me to finish work and basically follows me everywhere, asks me personal questions, makes comments about how attractive I am and begs me not to tell my sister, he also asked me if I was seeing anyone. Any other person would tell him to f* off at this point, unfortunately I am incredibly shy, so instead I get extremely anxious and try to change the conversation. I have been avoiding him lately and he noticed it, last time something similar happened he was extremely violent and rude towards my whole family (that's when I cut him off my life, surprisingly my sister blamed for everything). Anyway I cannot deal with this again, I don't want to be put in this situation, I don't want to be in the same room as him and pretend I am fine. I understand that my decision will affect my whole family, but I don't actually care, as my anxiety is getting really bad because of him. Unfortunately I will have to cut my sister and the kids off my life too, otherwise this will be never-ending and if I told her the truth perhaps she would just blame me. Just wondering what would you do in my situation?
