What would you have done before H left ? I have carried on just as normal with the estranged in laws and acknowledged all family events.
I have recieved nothing back up until this christmas, the in laws are waking up. H's stories have holes and the family are now seeing through them.
I feel we need to do what we think is right for us and our children. I agree with ACJ, a little note would be a way of communicating to show that you care and offer your support.
