Input: My son is turning 6.   His father and I are divorced.   We share custody 50/50.  My son’s birthday falls on my time and I’m throwing him a party for friends and family.  I guess when he was with his father’s mother he asked her if she was coming to his party.  My ex told me when he dropped him off that she would like to attend.   I said absolutely not.  

I’m not being spiteful or petty.  His entire family basically shut me out completely after the divorce.   I got no support from any of them even though it was my ex’s choice to end the relationship and leave.  His family was supposed to be my family too, and they all completely took his side.  

I don’t want them in my house.  They can have their own party during ex’s time as far as I’m concerned.  

not allowing any of my ex's side of the family to come to my son's birthday party
