oh Ellymay - I know what you are going through - sort of. Last year DH came in to our office and out of the blue told me he wanted a divorce. I was shocked and hurt adn felt like the carpet had been pulled out from under me...like you I had NO IDEA or CLUE he felt this way.
we went to counseling and obviously got some help. I discovered about my DH is he holds things in until the point he explodes - like a volcano. I have since gotten him to open up AHEAD of time before things pile up and every little thingdrives him crazy. You know what it was about me that bothered him to most - that I leave my coffee cup onmy desk all day long- it seems small but for him it was finger nails on a chalk board. It's these little things that add up...
It's good you have your own account - start saving and just take care of YOU. try to accept his apology but he HAS to talk about the issues.

mama. this is not what you need right now. My heart aches for you.
