I agree with SS's post on 10/7. Being less available will help, and no R talks for a while will also help. If your H tries to start the R talk, you can listen, but don't get into arguments or reason against his feelings. It's tough, but you can do it.
The most important thing now is that you can feel good about yourself knowing you want to save your M, and if for some reason your H doesn't cooperate, there is nothing else you can do. Don't give up. Be patient.
