I've given up my career to be a sahm. I wasn't a mega high earner but high enough at the age of thirty to be a higher rate taxpayer, with management responsibly for six teams of people. So you could say I had potential.
I did it as an active choice. DH didn't mind if I wanted to remain at work or stay home. I spent my twenties with my nose to the grindstone working long hours (as a result of company culture and presenteeism rather than absolute need, in hindsight). I wanted to 100% be present for my children in a way that I couldn't be with that kind of job. I also didn't want to put them into childcare. No judgement to those who do at all. But it wasn't what I wanted.
DH is a high earner, not quite six figures but not far off. He has a very responsible job, has been with the same company since graduation 15 years ago and worked his way up. He leaves the house at 7am and returns at 7pm. He occasionally works from home in the evenings or at weekends on a company laptop but not often. No company mobiles are allowed due to the nature of the work so that is a positive.
When he is here we split childcare and household responsibilities 50/50. Obviously he's not here most of the week which translates into me doing the lions share of the housework, admin and childcare etc. But that's fine with me. He couldn't tell you when the car MOTs are due; etc. Currently, that's part of my 'job' if you like.
It is about balance. DH has recently turned down another promotion which would have meant a jump in salary because he knew it'd mean longer hours and far more foreign travel than he wants to do. He didn't even apply for it, he was approached. He explained, honestly, to his boss that he needed a balance with family while we save small children (we have a toddler and a small baby) so thank you but no thank you, for now.
His boss has been amazing. He is such a valued member of the team because he works so bloody hard (without working all hours of the night and weekends) that they've arranged a semi-promotion for him with a smaller salary increase with a view that he'll take the other job in maybe five years. They want him on board, so he's been able to negotiate in a way that suits us.
Family comes first, for both of us. The perks of a decent salary are great, but not the be all and end all for us. We also don't feel the need to maintain an expensive lifestyle. Neither of us drive new cars, we shop to a sensible budget and don't have lots of expensive holidays. So if our income dropped, we'd still be ok without a huge change.
I hate it when people assume sahms are poor bedraggled women who only exist to prop up men's careers or that they must have just had a shit job before having children to have wanted to leave it. I didn't. I had a great job. I did love it. I just love being at home with my children more and my DH facilitates me If anything.
