Brief backstory. DH and I are in process of splitting up but still living together. Things are strained and I spend every evening sat in the bedroom to avoid him (if he leaves the pub to come home).
MIL is due to come and stay. I have asked her to cancel as it's not good timing. She is now sulking and being a bit cool with me. She has told DH that she wants to see her son and grandchild. Which is fair enough but I can't countenance her staying in this house and them playing happy families while I sit by myself upstairs.
Am I being selfish or is she? Her main worry about this split seems to be that she won't get to see her grandchildren. I feel she should be more concerned at this point for the fact that they are losing their family.
So AIBU and should I just suck it up? I know that she will arrive and expect me to join in with them as though everything is normal. I really can't bring myself to do that. I have nowhere else to go and stay while she is here. They can't go to her for various reasons.
