Hi Sandy, I don't think I've posted to you before, but I wanted to chime in and say that you are getting so much good advice from your friends here. I particularly agree with BobbiJo about trying to be positive and upbeat when you are together with your H. Focus on the positives, the things that are going in the right direction, no matter how small. I can understand your disappointment at him leaving while you were in surgery, but can you look at the positives of that day? He was there for you- even if he wasn't in the waiting room the whole time.
I also think that you should make an appointment for MC and tell him that you really want to start going regularly. I hope you can find a good C who can get you both to work on moving past the OW.
