My ex gf was the same way. Very abusive even physically although he was smaller than me but I didn't want to hurt her. She always threatened SUI when I said I was going to leave. I left her 6yrs ago after being together 2yrs. She didn't kill herself. I don't know what sees doing or where she is and frankly I don't care anymore. It'd be very ba if we ran into each other. I have very angry violent feelings towards her so I keep my distance. I hang out with none of our mutual friends or go anywhere she might. All I know is she got 2dui after I left her and she called me blaming me. I told her she did it to herself. She treats everyone around her like crap.
