During the party... she kept asking me why my children's grandmother didn't talk to her and does she know who she is and why does she come to a party and not talk. I didn't know why she was so interested in their grandma. She texted me and said your Mom's name is (blank) I said, yes. It turns out that she thought my ex husband's Mother was my Mom so she would have been Izzy's maternal grandmother that was ignoring her. Only it was my sons' fraternal grandmother that was quiet.
Edit. I am sorry. I meant to type when I am talking to my daughter. I feel like I can't say I do right by my kids or stuff like I take care of my kids to her. I wonder if I use the term "kids" to her am I excluding her? I would never talk to one of my sons and say kids.
