My sister and I live very far from other family (several plane rides and time zones away). I'm pregnant with my first, and despite me inviting my DSis to visit to visit/help with our newborn, she has cried off and said she will visit during her DC summer holiday when the baby is older (which, of course, will mean I will not be in need of as much help from her at that time!)
She is a single mum, split from her husband (I think that she cheated on him although she denies this, tbf I do not know the details as I did not want to get involved). I thought that after the pain of the split and breaking up her family, she would want to be involved in a happy event like the birth of her first niece/nephew. AIBU to be upset about this? I went to stay with her for two weeks when her first was born several years ago!
I have been trying to involve her in the pregnancy, texting to ask her advice etc. but all I get is breezy replies and best wishes. No real conversation or support. It's really getting me down. I feel alone, so far from family.
Because she is split from her ex, she uses the excuse that she can't visit for more than a few days because her parenting arrangement doesn't allow for her to travel for more than that with the DC. Surely this is something she should be able to negotiate with her ex? He is a good guy and tbh, probably too good for my DSis but that's another thread 
DH and I have contacted her ex separately as well and invited him to bring the DC to see us. He hasn't set a date to visit but seems more keen. Also, she is of the opinion that she can't take DC out of school to visit us. Surely this is more important, especially with her being my only family here? DC are reception/primary age so it's not like they're writing GCSEs.
Aibu to feel let down and out in the cold?
