I'm looking for some advice. ExH and I have 2 children together. After our divorce, he got remarried and had another baby with his new wife. He hasn't told me anything (and likely never will) but the DC tell me that his new wife has taken the toddler and moved back to her parents. This happened several months ago and they haven't seen either of them since.
ExH was abusive and our relationship is non-existent. I got an NMO to stop him harassing me and all communication goes through my DH. Communication is limited to arranging contact with the children. He lives a couple of hundred miles away. His new wife's parents live 400 miles away. I haven't had much contact with her but got on well on the rare occasions we met, until the last year when she started weighing in with exH's nastiness. After a couple of incidents I blocked her number and emails.
The DC miss their step mum and their sister. I want to make sure that they maintain some sort of relationship. She's obviously in a bad place (although hopefully better now she's left exH). I don't want to come across as gloating over their failing/failed relationship. I'm not. She's been an excellent step mum to my DC and if it hadn't been for the last year's events then I would have said we would have been friends on other circumstances. I'm sad that she will no longer play such a big part in their lives.
How do I go about reaching out to establish some form of contact?
