Should I invite my daughter's biological dad to her party?
He knows about her but he's not ever been in contact with her, never met her and I never asked him to sign the birth certificate or for child support and he's never offered any child support.
He lives a couple of miles away with his current partner, her teenage daughter and the daughter's baby (he apparently treats both as his own)
It's my daughter's birthday in December and I was thinking of asking him to the party. Am I mad? Should I just leave things? Should I invite him?
