Because when I was single, I didn't or couldn't. I got her pregnant. 5 years of hell with her, lost all the kids. She was insecure over Daddy and babies daddy before me, I didn't know. Coming from a man who has tried. Never again! Do you really believe she is going to care about step-anything when she insecure? 5 years of arguing about all of her insecurities to no avail. Time I will never get back. Oh and because I left her, she found and dated my brother.......THATS WHY!
