Don't mindread her ... you are far to much in her head guessing what she is thinking, feelings, even predicting what she might do.
Truth is, you know she had an A, that A may/may not have ended. She asks you if you guys should get a D lawyer ... if she wants a D she can file, this looks like a temp check to me.
She may be mourning the loss of the OM, you rubbing her back ... ugh.... really? "there there I know its hard I'm sorry you lost your lover" Let her cry .. .give her some space ... I get you want to save the M, but she needs to get to a spot she wants to .. Will you just allow her back into the M without boundaries? If you do ... she will give you a repeat performance with OM2 and you will be back here wondering what went wrong all over again. She has to respect you ... and to a point she may have to feel she is losing you ... so far ... you are there all to willing, so she can cake eat and play you all she wants at this point. Time to GAL, and detach my friend ... just because OM might seem to be out of the picture ... your W is still wayward.
