I wrote this early today, but apparently did hit the submit key. Anyway, after reading your last post, it sounds as if you had a R talk. Did you......or are you just rehashing things that have been previously said?
Okay, here is the post I wrote earlier.
Call your lawyer. Can you and the kids leave the family home and stay in temporary housing?
I don't think anyone blames you for being so upset. It is difficult to think rationally when we are consumed with rage. So, get a call into the lawyer ASAP, and ask plenty of questions about your rights. Then try to calm yourself down.
For now, I don't think it would be wise to say anything to your W about what she told your daughter, or how OM is lying to her. If you are like a lot of folks, it's real easy to make threats when you are met with defiance. After the heated argument over the gift situation.....I discourage you to dive into another battle that's sure not end well.
Cool down, stay as far away from her as possible. Get your thoughts off the OM, for now, and think about what you can really do about what your W tells the kids. Think about how it will be when you are D and she has them 50% of the time.
If you say anything to your W about what your D said, then your D may not feel that she can confide in you. So, don't let your anger lead your actions.
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!
