I don't get it.

I don't understand how you can hurt someone so much that you claim to care about? How can you see/listen to me cry and not give a damn? How can you insult me and call me names... then yell when I get upset? I am soooo confused it's not even funny. You claim to want to be with me, but the minute things don't go your way start throwing a fit(literally). I have 2 kids and I really don't need a third. Stop claiming you want to be with me and a few days later tell me it's not going to work out. What have I done to you that's so bad? I changed my life to have your little girl. I let you come around whenever you feel like it. I basically let you walk all over me and it's STILL not good enough. Will I EVER be good enough for you or should I just stop trying and walk away?
