Unless I missed something or a detail is left out, I agree that she does not have to even invite him. If there was any interest by him or he was contacting her possibly something could be different. But if he has chosen to make no contact and she has no desire for him to be there, why open any cans of worms so to speak. Though there is a part of you that probably is angered that your very special child will not have her father there, not the "way" of things, there just hasn't been the relationship there. So no reason to stir up drama. Sometimes the kindest thing in all respects is to leave well enough alone. (I eloped with a very small group to avoid having my dad at the wedding or involved in anyway. Didn't want to lash out and hurt him but DID NOT WANT THE DRAMA. So, quietly did what was most important to me and didn't open any cans of worms I did not want to deal with or hurt anyone.)
