To think she should have come in.

[Cheeseboardcriminal]

My ex has two children, one with me and one older child with another woman.

He moved 260 miles away but because his older daughter is close to her brother and I, I still have her over regularly.

Ex's mother spends every weekend with his daughter, her granddaughter. She has just dropped her off here for the night but didn't even get out of her car despite her grandson (my dc) being inside.

I don't stop her from taking my DS out with them or make her unwelcome in my home. She says DS just wants to come home when he goes out with them. Which he probably does because she hasn't built up a relationship with him.

So AIBU to think it wouldn't kill her to pop in and see him and ask how his day is when she is literally here anyway dropping off his sister.

that must hurt seeing your son cast aside OP. However you cant force a relationship and its her who will lose out in the long run. Sounds like your son has a loving family around him anyway

I do find it very annoying, my son doesn't actually notice or if he notices he doesn't care so its not an issue for him but one day it might be.

Its a regular occurance too.

His sister spent Friday night with their joint grandmother, then they went to the cinema today and she can't even pop in to say hello to him. Ask if he is looking forward to going back to school or whatever.

There are 4 years between them but DS is junior school age so not like a baby and a more independent child.
