I just want to add here that you will be connected to her always because the children belong to both of you.

At some point you will need to sit down and talk about how the interactions between the two of you are affecting the children. Always remember you are a father and don't think of your time with your children as just babysitting. Get to know them, sit and read to them, do things with them and love them as you ARE their father, no matter what happens between you and your wife.
