I do think that women find themselves in predicaments when a spouse leaves them suddenly or passes away. Money is tied up and often the woman finds she is unable to support herself due to not having worked her whole adult life.
I have a friend who's husband passed away several years ago. They lived out in the country and had 4 kids. She lost her home and everything they owned because she didn't have any skills to fall back on.
She ended up going to college and finished in 3 years. She lived with her mom in a 3 bedroom house with mom, her, and 4 school age kids. It was chaotic and stressful. She graduated as soon as she could and then had to substitute for 2 years before she got on full time as a teacher.
She's been working for a couple of years now and is finally out on her own in a modest 3 bedroom home. She misses the large home with land she had and her "life of leisure" as a stay at home mom.
I think once the kids are older and in school that all women should not be dependent on their husband for even spending money.
Your son may feel the same way. It's his opinion of course and he can have it just as you can have your opinion about why you like staying at home taking care of the house.
Ask him why he thinks you should go out and find a job. Perhaps even taking a job that someone who is trying to find work to support their family. You might also just cut him some slack too if he's in an area where they are at war because he might not come home and you'll have those last words you said to him for the rest of your life.
Letting him have his say and perhaps validating him in some way might help you both to come to terms with his anger at you.
