She is busy with business, house, kid and her, you know, fiance. Which, BTW, also has me on edge. I, as a rule, never involve myself with someone who is already otherwise involved. But, she had said she was not married in the beginning, which is technically true, I suppose, and also, what's done is done.
If she is willing to sneak around on HIM then she is willing to sneak around on YOU.
