So this guy who is my friend wants to date me I said no like 100000times he doesn't get the hint he is very emotionally abuseive he threatenns to kill himself over me and makes me feel like it's my fault he has chocked me out in the past.. He's very obsessed with me doesn't like when I have other friends or talk to anyone else last night we got in a fight like always and he ended up throwing a glass plate at my head and screaming in my face saying that I am playing head games with him witch Iam not I am very clear about not wanting to date him and how I Need space because he wants my attention 24/7 and shows up at my work place Unannounced uninvited and constantly wants to argue with me.... Im afraid that of I end the friendship he will hurt himself and it will be my fault he has tried In the past when I tried to break it off he stabbed himself in the chest saying it's my fault I ruined his life and I am to blame if he dies.. But after last night him freaking out so bad throwing stuff at me I really can't do this much longer I was thinking about maybe getting a PFA on him because I don't feel safe my anxiety is sky high.... Been having panic attacks every night for a while... Anyone know the right thing to do?
