Rppfl I'm not so sure about the working out thing. My dad left when I was eleven and it's taken almost 35 years for us to reconsct My two S still live their mum and show it but they don't know who she is now and treat her quite off hand. I encourage them to interact with her , which they do but only to a point. My two Ds act like all is ok when W is here but they are very sad on the inside.
For me the WAS must have a mental blockage when it comes to their kids because my W was a great mum and now it's like she's a bad aunt
