How many times am I expected to be left and abandoned by someone and still want them to be apart of my daughters life? How am I supposed to know that she will not get her heart broken like I have over and over again? I don't want that for my little girl. For her to love someone with all of her heart only to be left with nothing but broken promises. She doesn't deserve that. Why would I want someone who I have no idea if they are going to be there the next day to be there when I bring my sweet innocent little girl into the world? It's not fair to her and it's not fair to me.
