I am a totally single mom. I asked my ex to leave when DD9 was 5 mos old due to a problem with alchohol. It was not my intent to have him out of her life, that was his choice. He agreed to child support, but has paid $250, and is now close to $50K in arrears, and has eluded all attempts by several states to locate him. I even had difficulty divorcing him w/o his signature, but finally got that completed last year.
We do not need him financially, and I know that unless he has made dramatic changes in his way of life, that DD is probably better off without him in her life The man I knew would have broken her heart 100x I am sure.
Every year, the wish she makes when she blows our the candles on her cake is that he will come back for one day so she could meet him. Breaks my heart! I can't deny her that wish, and for her I hope that one day when she is old enough to make the decisions that maybe he will re-surface to see what a wonderful kid he missed out on raising, but it wold be a very difficult time for me!
