My H has listed in the past the things *I* would have to change in order for him to 'come back.' Other than the silly infidelity, he doesn't see a thing he would have to do. I have told him that is simply not true, but would not list anything for him, as he isn't anywhere near able to listen.
Puppy is needed here.
I have a feeling you shouldn't 'back down' and remind her that this is about BOTH of you repairing this marriage together and yes, because of the trust she broke, she will need to help rebuild it.
Mac is right, she can't see now that meeting you at least halfway would really help things.
