So sad to read. I bet you never thought she could be capable of this level of selfishness and hatefulness.
Be very, very careful what you say to her. Arguments will cause you to say things that come back to bite you hard. She will use everything she can to get what she wants.
Please do not make threats about the OM. She will do things out of spite....just to show you she can. I don't know the laws there, but where I live, it's not that easy to place restrictions on who your ex introduces to the kids. I think you can restrict "sleep overs". Anyway, find a lawyer who will work for a father's rights.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
