So, DH and I moved out of area 20 years ago. 6 years ago my SIL, her husband and kids moved up near us. The parents in law visit fairly often and stay with them, never with us although we have room. They always spend the majority of the time without any contact with us or seeing my kids. When they do visit, it’s 95% of the time with at least one of their other grandchildren (my kids cousins) in tow. This Christmas was the final straw for me. 7 days at the SIL. 5 days without seeing us at all. They attended one of the kids Christmas shows (not either of mine), went to panto with them on Christmas Eve, basically having a lovely time. Popped over for a max of 2 hours on Xmas day , everyone came to us Boxing Day and we were invited to join them all today for breakfast. They’ve spent every Christmas Eve and Christmas morning with the other family, never with us. I invited them for a walk after breakfast today but they couldn’t manage that. I’ve had enough. AITA?
