Kramer VS Kramer 2/ Kiron

In my honest opinion, I don't think that Joanna is justified by leaving Ted and Billy all by themselves. She basically left because she needed time and space to try to find herself. I believe that if she wanted time to herself, she should've done it before her son was born. It's not Ted's fault that he has to work all the time to provide for the family, and Joanna quit her job just to take care of Billy, so what seems to be the problem? The other thing is, Joanna left without warning towards Billy so of course things were going out of whack with the family of two. Then she had the audacity to take Billy back with her to live. I personally hate something like that, it's like a dead beat father but the mother is one.
