Background we have 2 DC are doing ok financially DH has had a few promotions and we can comfortable afford the house we live in and holiday, kids activities etc.
I have reduced my hours and work part time. Not rich but comfortable.
Downside DH is stressed, works late all the time, grumpy and during the week I may as well be a single parent. Knew about the long hours would be on occasions but seems to have increased. DH tells me this will improve in the next few months hopefully 
Weekends are hit and miss often DH will spend some time replying to emails but we usually have some good family time.
We don't have any couple time and although I have complained he hasn't done anything to improve it. He has suggested days out just us to but I will need to arrange someone to have kids etc which will be nice but will be a month or so before I can arrange it. All I really wanted was a night a week we eat tea together and maybe watch a film or something! I have said this and he has said he will try but I phoned home before sorting my tea and he said he will be home late each time .
I know he is Under a lot of stress and work and I don't want to add to it but I don't want to live my life like this. I have always said money is nice but you spend what you earn so as long as we can cover the bills I'm happy.
Ive started to become insecure because of the lack of time we spend together and I want family and our relationship to come first.
I can't see how it will if he stays in this job but I know he is proud of what he has achieved and may struggle to get another less stressful (and lower paid) job.
I don't know how to raise the issue of possibly downsizing and him changing jobs especially as he keeps sending me links to more expensive houses on right move to look at!
I'm afraid he will value his job and money over our relationship/family and his health (the stress can't be good) he is struggling sleeping/ dealing with stress.
Sorry for the long post
