Single mother of one

Hello everyone I am just writting my thoughts out weither or not anyone reads them and if I affend anyone I am sorry. I am a single mother of one beautiful 2 year old girl !! She is the most beautiful girl with long curly redish blonde hair and blue eyes. Every one who meets her just falls in love with her so why did her own father not fall in love with her?! I understand some times the fear of taking resposiblity but then again I dont cause I am the one who has to take the resposibilty while he goes out and parties and does what ever else his little heart desires... Now I dont want him back not now not every but why cant he just grow up and be a man for his daughter. I know plenty of guys who dont have there kids but still want something to do with them and helps take care of them. He does nothing and just wants to see her when it is best for him. He has not helped me take care of her does not help me buy diapers or food or clothes or anything I need from him and for her. I have child support in the works but boy does that take forever cause they cant find him he is always moving always getting kicked out of where he is staying.I am seeing now in my angle that she really needs her daddy. All children need their fathers God made them that way made each of us that way. I got the chances to place my son and he now has a father but my daughter who I could not live with out I have and love dearly. I see it in her so much of how she needs a dad . My father was in cancun for a week and when he came back she clung to him and was always calling out "poppee" for the entire day ! She needs that male figure but becuase of her fahter she wont have that daddy right now I am happy that she has my father to give her attention but it is not the same as an actual dad ! Why do most men never get over them self and just want to do what they want to do that selfish tendisy just doesnt leave some. Oh course I have had the wrongest expeirnce with me and most might not be like that ( half and half maybe ) I just dont understand why my angle has to go through this. She never did anything to him .... I guess in his eyes she was born but that is just an excuse ! He calms that he loves her and wants to take care of her but for 2 years it has been the same thing. He just up and leaves and doesnt call or write for 6 months at the most then desides he wants back in well I am ready to pull the plug on that and I know it will make him mad but what else can I do
