Im sure that they are positive signs... but you still need to be keeping her at arms distance. Dont swoop in to rescue her. If you make yourself attractive enough SHE will be the one to make reconciliation an option, either through her actions or verbally. Have you at any point told her that you dont want a D, or that you want to reconcile? If you have then she already knows, you dont need to repeat it. If you havent said it yet, Im not sure that now is the right time. And just because she says that the friendship is over doesnt mean that it really is.
Do you have 2 kids? I still think that seperating them is a terrible thing to do, if she cant handle them, then you should take both of them.
I guess I gave the wrong finger to the wrong man...
