I know the example I gave you was extreme but I wanted to illustrate to you an instance of a father who put his child first however much it hurt him. I don't expect you to react in such a strong way.....but at the moment I do not think you are putting your children's needs first. I think you are using them as a reason to argue/ harbour bad feelings towards your ex and I think that could backfire. A little give and take is required. If your W takes that specific time away from you then she needs to give back time elsewhere.
