You can also tell her that your attorney believes that children, especially young children are better off in primary custody with their fathers and he/she told you that that is the way the courts are going these days more and more. Single mothers with children have a difficult time juggling life, bills, boyfriends and children. I'm not knocking single moms who usually do a tremendous job but generally men that want primary custody tend and fight for it, all other things being somewhat equal, tend to do a better job of raising children.
Wouldn't this affect the outcome if hes trying to get her back? or even backfire with the courts?
