PIL live less than 5 minutes walk from us. MIL is retired, pops over about once a week to see DS (4 months, their only GC). I pop over there now and again but it's easier for her to come to me because they have a dog who is all over DS, all his stuff is here and often when I do go over she's not there or is on her way out.
We go over there whenever we are invited and vice versa. She calls in here uninvited (no problem with this) and sometimes I call in there uninvited.
PIL are about to go on holiday for 2 weeks. MIL popped over briefly this afternoon to see DS before she goes. She had a dig at me because she thought I might call in to see her before she goes.
I think part of the problem is her only other child (daughter) lives 3 hours away and has no intention of having a family, so she doesn't have that mother/daughter/grandchild relationship and I am the substitute. Don't get me wrong, she is lovely and we get on, but in the nicest possible way, it's not the same as with my own mum.
AIBU to think that if she wanted me to call in she could've just said? I didn't really know when they were leaving other than it was some time this week (she may have said but the exact dates of their holiday are not at the forefront of my mind when I'm sleep deprived). Or AIBU for not calling in there without an invite so that she saw DS before they go? AIBU for not calling over there more often , even though it is much easier for her to call in here?
