Sorry the conversation didn't go well. I feel partly responsible, though it does sound like she is sending mixed signals. This is not uncommon in these sitches. The important thing is when the discussion starts heading down hill, to difuse it quickly. What Lola said is a good approach now....go with the flow. I would make GAL with your kids.
I do think you have said your peace with the OM....now I would let it be, you know the reaction it will get you and there is little you can do to prove otherwise that wouldn't destroy your M anyways. Also she won't accept any blame (at least to you) at this point.
Don't be afraid and don't tell yourslef it is all your fault. Accept your part. I do feel she is trying to lay everything at your feet. Remember to believe nothing of what you hear and only half of what you see.
You are by no means at the end of the line.....she still hasn't filed and even then there is hope if you want it. 19 years and 2 kids is lot for both of you
