@whatatanker Congratulations! Good decision.
I hope your dh can join in and be excited for you too.
I'm at the other end of my career spectrum but when I was young, getting married, planning a family, I expected that my career would take a back seat. It was the way that it went during the 80s and early 90s when I had my dc.
In reality, I felt unfulfilled and lonely. So to the horror of many, I returned to work - part-time for a while, but then full time. My dh was very challenged initially. He had enjoyed both the practical benefits of having someone at home and the social kudos of being 'the provider' for his family. He felt embarrassed (his words) pushing the pram to take dc to the childminder - no other dad did that.
We worked through it. There were problems at times and it wasn't all smooth sailing. But I was definately a better and happier person, mother, wife because I felt enthused and energised by my job. I also had a subconscious sense that because I had 'my own money' that I did have a choice about my life and relationship and that therefore I was continually choosing to stay in that relationship, rather than being stuck in it and having no other option.
Over the years, combined incomes have allowed each of us to take risks and options in our careers and during covid lockdown we were so glad about the decision we'd made years before. We'd have been f&ked if only one of us had been working.
Now we're retired (sort of - there's still some self employment work going on). We both have pensions. It's very very unlikely that we will ever split up, but even if we did (or if one of us died) we could both survive independently. Ultimately, we're still together because we choose to be together not because we have to.
I know that 2 parents with busy jobs is not right for everyone. I have friends and family who made very different decisions and who now, at similar ages to me and dh, are equally happy with the choices they made. There's no one right answer.
