Apologies in advance for the length of this - trying not to drip feed.
DH is a high earner and has worked very hard for his whole adult life. About a year ago, I became a SAHP, but prior to that I had worked similar hours to DH. I am slightly younger than DH, so had not worked these hours for as many years. In addition, my profession is a bit lower paid than that of DH and frankly, he was unusually successful in his profession, whereas, whilst competent, I wasn't exceptionally successful in mine. As a result of his career success, we have had a comfortable lifestyle, paid off our mortgage and whilst we don't spend excessively (both of us being from quite frugal, sensible backgrounds), we have been extremely fortunate in that we haven't had particular money worries. I know that we are very, very lucky.
When I became a SAHP, this was a joint decision, although a contributory factor was my mental health and the impact on it of a horribly stressful job. Even today, one year on, I quite often find myself in tears and sweating at 3am about the situation I left. We decided that it would be best for all of us if I were to be a SAHP until all of our DC started school. We are now expecting DC2. DH says he still feels that it is best for all of us if I continue to be a SAHP for now. I was happy with this until very recently, having taken steps to protect my own financial position etc. DH's job is very demanding and it is true that I don't think he could do it if I were doing my old job and unable to be the "default" parent, as I am now. We live in an area with very little childcare provision and my returning to work would realistically mean DD being in childcare from 7 am to 7pm every day, which I would prefer to avoid if possible.
However, DH now says that when the DC start school (so in 5 years or so), we need to share the financial responsibility for our family down the middle. So far, so reasonable - I was very much intending to go back to work. We have worked out a budget as to what income we will need to meet our outgoings. However, what this means in practice is that from his high earning position, he will only need to work 1 day/week. Even when I manage to get back into the workplace, it will mean me having to work 5 days/week, because I will have disadvantaged myself so much in career terms. I feel that my being at home has directly contributed to this situation - increasing his earning potential massively and reducing my own - and that it would be fair to take account of this. I pointed out that if I made a unilateral decision that I was only going to "work" in looking after the DC 1 day a week from now on, he'd have serious difficulties. I feel that it would be fairer to, for example, work three days a week each, if such roles could be found. He says that he has worked hard for many years and deserves a break. I feel that I could say the same, but I have a (shared) responsibility to look after our kids financially and emotionally. Being at home with small children isn't a holiday and I feel that it's not fair for me to do all the years of wiping snot, night feeds and chasing poo around the bath and then for him to want to swap and be the SAHP once they're both in school and he can read his book on the sofa.
I'm also a bit upset because we have always had shared responsibilities and finances. He's an amazing father and he worships the ground DD walks on - he's not some sort of absent parent and I would never, ever have said that he was someone who shirked responsibility or was looking for a free ride on the domestic front. We are a family - we have always mucked in together. That's what families do, isn't it?!
AIBU?
