After some advice....
I have had an intense period of stress, through setting up a business and other projects. This has kept me away from my family, sometimes seven days a week. Whilst at home I have not been engaged and have been tired. I believed that I was doing the right thing, but can clearly now see my priorities were wrong.
During this time I have been quite miserable at home, mainly as I haven’t seen the kids and work a stupid amount of hours some days. I have not been fun to live with, and have spoken to my wife unkindly a large number of times. I have said things that I have not meant when we have argued and have generally not been myself. I have not been helping with the kids or house, which put a lot of pressure on my wife too. I have been quite self absorbed, isolated and in a bad place. I didn’t realise.
We recently had a large argument and my wife has said things are over. This hit me and I could see where I had gone wrong. I have thought a lot about the mistakes I have made and I have apologised and accepted that my priorities have been wrong and I have also apologised for speaking badly to her which I deeply regret. I have started doing all the housework and putting effort back into helping with the kids. I have also suggested we try days out again, but it seems too late.
I have acknowledged that I have got angry and very stressed many times and I am now booked in for help with this.
I really don’t want to loose my wife, as I love her very much and am after any further advice about what I can do to improve this situation.
