Single Dads Support Group
This community is dedicated to fathers who are going through the parenting process alone or without the support of a spouse. Single parenthood is often opted for by the parent (as in divorce, adoption, artificial insemination, surrogate motherhood, or extramarital pregnancy), or an unforeseeable occurrence (as in the death of one parent or abandonment by one parent).
Why not do the party regardless of what your STBX wants? She doesn't have to be there, & just because she doesn't want to do it doesn't mean you can't do it without her.
You said it in your last line of your post!!!!!
Now go party!
I have to talk to my daughter and see how she feels. I may have other equally fun plans.
To make it up to her a few weeks after I may plan a play-date for her at the McDonalds playland with her best friend.
