My fear of sharing Standers with my H is like you say-I don't want to inflame the situation, or make him feel more guilty. We are both Christians, and I know it would make him feel really bad...not that he doesn't anyway.
I just want him to know how committed I am, but then again, simply by being here (and not throwing his sorry butt out!) should be proof enough-for now.
We still say "I love you" daily...course, we did that too while he was taking on with OW so....I do not question his love for me, I question his love for himself (which in turn also affects his ability to love me).
