Obviously I meant to say journo...and partner instead of spouse!
Also to add to my non-exhaustive list:
Funds for household help such as cleaners (I couldn't work full time without a cleaner and keep my sanity/have time to spend at weekends and evening with my son)
Desire to be independent from a partner
Desire to be equal to a partner.
More time for hobbies/sport
My desire to work full time is partly from my mum who was a SAHM. She definitely shaped my future and I am very grateful to her for that. Society kind of expected her to give up work, there was no part time working provision the in the nursing shifts she did..But when my father stopped earning so much as his work changed due to technology later on she became a bit bitter about not having the luxuries anymore. She also had no earning potential as her qualifications and registration had long ago expired and her confidence in her ability to work was rock bottom. I've internalised a lot of guilt about the sacrifices she made for me. We didn't get to go on big holidays abroad and I didn't go to theme parks or Disney world like many of my friends. I did have a lot of toys and things. She couldn't afford to spend much money on the house which really desparately needs it now. We couldn't afford a sibling. And her relationship with my father is not great, however she is almost completely dependent on him so will never leave. Due to the earning imbalance my father thinks he wields all the power over her and doesn't seem to recognise that she gave up her career and earnings to raise his child and basically him with his 1950s attitude of women. If she left him however she would be financially worse off ironically as she has had to save for her future, he hasn't bothered. She was also hit by the government pension changes which means she doesn't quite qualify for full pension or it doesn't start when promised can't remember which. I remember my mum was always cleaning the house. So even though we did get to spend a lot of quality time together, I still managed to resent that (as a child, not now!). She also became my primary source of entertainment a lot of the time which wasn't particularly healthy.
All of this affected my decision to work full time and she actively encouraged me to be independent due to her circumstances. That's been the right choice for me so far but not sure it will always be the case. Circumstances change!
The point of sharing all this is you make the best decision you can at the time based on the information you have at the time, no one has a crystal ball. Which ever way you choose though there will always be pros and cons and that means there will be guilt/sadness due to the consequences of the option you didn't pick! That might be less money for holidays or less time with the kids than you'd like..Doesn't mean those feelings aren't valid or should not be expressed! We just all need to simmer down and be and let each to their own.
I still wonder why not many men work part time (although I know a few now!), I think that tends to be down to societal expectations and gender paygap in a sort of self fulfilling prophecy/ endless loop!
