Please read a thread I started. Google the following "Depression and sensitivity - a connection? -Beyond Blue"
To fin success in your relationship both persons need to be fluid about helping it along. I tried for 11 years with my first marriage and I was the only one trying. My then wife needed help to realise that she had an overworked husband (working 3 jobs so she could be a stay at home mum) and that she was lazy (no housework, no meals prepared etc). Essentially my wife was not fulfilling her side of the agreement. Towards the end I was desperate. Heading towards suicide thoughts I rang for a home visit from our GP. There he was sitting opposite her at the kitchen table dressed in her dressing gown at 2:30pm. I told him I'd got up at 7am, fed the kids brekky, sat them in front of the TV, mowed the lawns, fed us lunch. My wife will have brekky at 3pm and wont want dinner at 6pm when we do. He took some blood for tests.
A week later he called me and I visited him. It seems to me a case of laziness was his diagnosis. Two husbands after me and both left her for the same reason- contemptuous attitude.
Here's the deal- had she sort help early on, had some insight instead of stubbornness she could have saved her marriage, our children could have had their full time dad forever and I could have not had to had my life turned upside down. Lots of consequences.
I bid you good luck and we are here anytime.
