Do you see now,JL, why I was not convinced H really was here for right reasons all these past 6 months - and I can't help but wonder now. When I mentioned the option of separating - and giving him a chance to see her freely to either get her out of his system or into it, he actually considered it. They're hard emotions to get past. Go back and read some of New Beginning's stuff about her guilt. How badly she felt after her one-time sexual thing and how hard it was for her.
Guilt is so very powerful.
Do NOT doubt yourself. The only pull Robert said sex with her had, the only real advantage was that it was new and forbidden. That's a big thing. But that doesn't last. Calm down, give it time.
