This is also my life and I'm extremely grateful for it even though it's obviously not as perfect as it appears from the outside. I can sense that I've lost some friends over the years as a result even though I haven't changed at all as a person. I'm aware of the "unfairness" and difficulty of today's economy plus the pressure, especially for women, to make things happen that are largely out of your control. So I can understand why some people have dropped contact and it makes me a bit sad but I know there's no point pursuing it.
The broad answer to OP is that my cultural background places a lot of emphasis on choosing partners with "good jobs that can provide for family". This is not seen as gold-digging but mostly common sense, as choosing a partner is one of the few things you do have a choice in. When I started dating my husband we were both students, and he had absolutely no money but was studying medicine. He was a kind and funny person as well so my parents were happy to give their approval.
We spent many years just hanging out with friends, going on cheap road trips and fitting life around exams, work placements etc. I was self-employed with my own business and he graduated as a doctor. Because it was such a long process, it didn't feel like a drastic lifestyle change. All our friends from uni were now doctors as well but they were still the same people. And by a freak stroke of luck, I was self-employed and my business took off which actually supported us for many years. We managed to get a mortgage on a dream home using my deposit.
To be honest, we are fairly "boring" people and the same applies to all the couples we know who have happy, comfortable lives. We spend hours talking about tax which would bore the tits off anyone 😂. People might see the occasional holiday snap on FB or glamorous work event but those are few and far in between. Our weekends are spent doing admin, filing papers, buying food or maintaining the cars/apartments (as many have mentioned there's a shitload of work that comes with extra material wealth).
I continued to work throughout my maternity leave as I love my job, and we had a lot of problems as a result of uneven childcare. I had to accept that I chose to stay home with our daughter so I also have to give up part of my career that I was so proud of. I struggled with PND/A and no amount of money could have made that better. I still get lonely a lot and our daughter is so young that I don't want to leave her with a nanny or nursery yet. I love what I have but I'm secretly envious of people with freedom...students, young people, single people, older couples. The joy of being able to come and go whenever you want, sleep in, take a spontaneous trip, go shopping or drink a coffee without looking at the time.
