I think she is awful and questionably stable, no children, very shaky first M, no friends. I think she is using H, and he is using her.
I couldn't agree more. My xH still won't admit his relationship to the woman he "boards" with. She was never stable, never in a long term relationship, never married, no kids, no friends, 50 some odd years old and about 100 or more pounds overweight. What a winner. But at least in compared to her, xH can feel like he is higher up in the pecking order.
And to think, he gave up the respect of his children, his relationship with them, a wife who loved him, and financial security!!
