Rtl just to offer a different perspective, from someone who has raised 3 daughters, your D does not care what your issues are or your W's. She is turning 5, she is having a party, cupcakes, presents and friends, she wants both her parents there, she is far too young to understand, if her Mom says she invited you and you don't come, she will be sad. I know it is not easy, but don't miss your daughter's birthday party, no matter what W does, Don't cheat yourself, you don't get to go back and do it again. Don't give the Om that kind of power over your relationship with your D
