paj-I too feel this way with xabf. He now has a really good job, over on the coast, and he gets to enjoy that scenary. It makes me somewhat angry now, as he just walked away from any and all responsiblities. I guess like anvil said, they take the easier way out.
I totally can relate to where you're coming from. Although my son isn't with my xabf, my son's A father did the same thing when he left me. Actually I was pregnant and he left me for a 18 year old girl that was still in high school
(I was in my early 20's at the time) I raised my son alone for a very long time, and he only popped in to be the "disneyland Dad" on occasion.
Hang in there sweetie
