Mopsey, You sound like you are in a much better place these days. Look at what you posted! You are calmer, enjoying life a bit more and no, you aren't sitting around on pins and needles waiting for the other shoe to drop.
Your h sounds like he's coping better. Maybe the reason he appears a little bit happier is because he doesn't feel the "pressure" of being analyzed by you and/or watched all of the time. They do sense when you are waiting for something.
Continue to go w/the flow and allow the man upstairs to do his work. Enjoy your time w/the children and soon....spring will be here!
