Daughter's father in and out of the picture for the past 17 yrs now he blames me for it.?

My daughter's father has been in and out of her life since she was born 17 yrs ago. He disappears for months sometimes years at a time. He promises her all these things and never follows through with any of them. He recently contacted her via myspace after being out of her life for 3 yrs he said he wanted her and him to have a father/daughter relationship and that he would be there for her and not be in and out of her life like he had before.. My daughter hardly knows this man and it is not through any fault of mine he would disappear and never contact her the last time she had talked to him before this was when he called her from the emergency room and told her he was being admitted for heart problems. that was 3 years ago. he did not have a phone so we had no way to contact him. so against my better judgement my daughter agreed to give him one more chance. Well low and behold he is doing the same things again.. this time he is blaming his behavior on me saying I am a control freak and a person of less than normal intellect. All because I am not comfortable with him taking her out by herself and and letting her spend the night over at his house.. this man is basically a stranger to our daughter and she does not know him.. When she was a baby he brought her over baby clothes in a box that had kitty litter in it. She has been in counseling since the last time because of the rejection he caused. Am I being unreasonable? I have no problem with him seeing her but she does not feel comfortable being alone with him. I told him that but he does not listen to me. He thinks it is me controlling the situation she is almost 17 and has a mind of her own she chooses not to call him. My daughter has mental health issues she is bipolar and suffers from depression and I do not want her to transgress back to the way she was before the counseling.
