Your spouse ends your marriage, which was never a very good partnership. Or maybe it was, until it suddenly wasn't. As such, it is natural for you to also feel like you are the better parent and that your kids should live with you.
If you find yourself in this position, it is important to remember that someone does not have to be a good spouse to be great parent.
For instance, one woman said that her husband told her he did not love her, and they got divorced. After the split, their relationship was not strong and she admitted to making him feel unwelcome in her house — the same house they lived in while married.
A family crisis caused her to once again depend upon the children's father to shoulder some of the custodial parenting duties. Because of this, she eventually came around to the idea of 50/50 custody. One turning point was when she put the girls to bed and they cried for their father. She realized then that, no matter what her relationship with her ex was like, he was still a good father to his children. She even went as far as to say that he was doing a great job. It was clear that he loved them and still had a close bond with them, despite the end of the marriage.
It can be hard to find this perspective in an emotional divorce, but it is important to attempt to do so. Both parents need to know that they have rights to see their children.
