GH, you know I can relate to you on this issue. I agree with your C to back off and lay low. Without realizing it, we are probably coming off as needy and desparate (which we are) and that is scaring our spouses off. They have to WANT to be with us, we cannot force them. It needs to be spontanious. Imagine if you were to get together and her heart wasn't really in it, how terrible you would feel.
I'm glad to see that you didn't get sucked in by her mood. You broke the cycle and in turn she cheered up. Way to go!!
