So, I was the wife in this situation.
My husband did fuck all around the house and I was responsible for everything. I used to try and be understanding, as he had a busy job and I did the lions share of the caring for the kids despite working too.
If I asked him to clean, pick up his socks, tidy, do a job...it was construed as nagging. I was depressed, miserable and unhappy, but he didn't even notice or care.
His soloution was to have an affair with a woman who didn't nag him, who didn't have kids...while I continued holding our house and home together went through all the hormonal having a baby bit, and looked after our disabled daughter.
I was quite arsey, and nagged at times and was distant..mainly though the sheer amount of stuff I had to juggle daily and all the household family stuff there was to do head at piled up in my head.
In the end, he decided that he would leave, his wife and kids for this woman who constantly reassured him how utterly awful I was.
So he did, and three years on his kids still suffer, they write stories down about the time their dad left, and cry at the fact all their friends have a mum and dad at home, and even fucking topsy and tim do in their books.
They don't understand why he left.
You need to take a long hard look at yourself and your marriage, because what happened to us from thoughtless selfish actions has had horrific repercussions for us, our home, our lives and my children's self esteem and confidence.
All because "she gets me in a way that you don't"
I didn't have time to get him....All I did was try and keep our family together, and essentially care for an ex husband who was like a third child. I would often suggest time away, some time together, which he never took....he never bothered to do anything lovely for me. When was the last time you did something for your wife? A weekend away? A night out? The day he walked out, he had nothing to tie up...every bill, financial thing, everything related to household was run and organised by me.
Is this you?
