My so called mother was never there for me growing up. She left my father to raise my brothers, my sister, and me all by himself. She left the family to be with some jacka$s dude and she never paid any child support despite the fact that she made more money then my dad at the time. She never visited or made any effort to be with us. The other day she found me on Facebook and tried to contact me. I refused to message her back and blocked her. I still feel angry at her. If she died, I really wouldn't care. IIN to feel this way? Should I try to mend things?
