For the past 8 years we have tried to get MIL to be an active part in our girls lives.
There were a period for about a year where she wouldn't have anything to do with us because the issue was raised about how she never really showed any interest in them.
We have attempted to reconcile over the years and think we are getting somewhere and then it all goes quiet unless we put all the effort in.
We call her occasionally but not regular because the conversation always ends up back to her and she never asks anything about them or to speak to them. If we say for example X is in at the moment would you like us to shout her down and you can have a chat she says yes but never asks herself if they are in or calls us. We haven't been to see her for a while because of how little interest she has and it was always us visiting. She's been invited to stay for a weekend, many times but doesn't take up the offer.
Should we accept that nothing is going to change after all this time and she isn't really interested and we can't make her be an active part of their lives.
