I'm not made for romance too, but maybe in a different way than you.
My previous girlfriend threatened to kill herself if I break up with her. I know she couldn't kill herself but imagine the mental stress it brought me. My first girlfriend still communicates with me at the moment with these subtle messages of killing both ourselves and obviously blaming me for ruining her life (and making it pathetic, so she claims). Girls/women are great, but somehow, when they're involved with me, they turn psycho and i'm the one that gets pawnt/gets headaches. I've had enough, i'm enjoying my single life now despite the threats from my first girlfriend. The one that threatened to kill herself stopped communicating with me, maybe she did it, just to make me guilty and make me regret that I loved her.
