Not sure where to start.
MIL and OH had a disagreement about her lack of involvement with her only grandchildren and OH told her it's upto you when you visit/call etc but you can't keep letting them down.
For the past three years we have had a limited relationship whereby if we didn't skype/video call or go down she wouldn't bother with them.
For a year of the three we had no correspondence despite OH trying to get her to show an interest.
She tells the world she loves them and misses them and that we are stopping her seeing them. We are not stopping her, we both work and both girls are now at school and have numerous activities. I don't drive so rely on OH to run us to weekend at activities. We have a spare room and would love nothing more than her to stop over.
Last year at a family event that we all attended she actually did small talk with us and we thought everything was sorted that night and the girls looked forward to seeing her again. We tried calling her and skyping over the next six months all to no avail. September for some reason she actually answered a text and said she couldn't log into skype so could we video call via messenger and she was really enthusiastic asking the girls lots of questions and asked OH to contact her in a couple of weeks to sort another call out. We did, to hear nothing, we have sent several messages but haven't had a reply.
Well today find she's blocked OH on messenger, which means we can't video call anymore and have spoken to a family member who tells us she's fed up of us cutting her out of the girls lives and will see the girls when they old enough to visit.
OH was getting fed up of being ignored and was hoping with it being Christmas she may answer a message and we could try one last time.
