It is wrong if I'm not going to invite my daughter's former stepmother to her graduation?
Did your daughter choose to no longer have contact with her former stepmother?
No, it was my choice.
If she wants to come you should not ban your daughter from having a relationship with her. It is wrong to keep kids away from parents they are bonded with.
It's none of your business. What it's, is my kid and her family's business. I've already chosen who should be invited.
If her former step-mother has not reached out and asked about the graduation, it's fair that you don't go out of the way to extend an invite. You know best how your daughter feels about her former step-mother and if it would be beneficial for her to be there or not.
