I guess do what ever you feel you can handle. I have had my H there on christmas day before. Its tolerable. We are friendly. We have kids together. If you think you can handle it, then I say invite him. You are parents together and there is going to be lots of things in the future you will have to share along with your daughter. The way I look at it is how could it make anything worse.
