Yeah, mozhe.
When I said that I wanted my dds to do what made them happy and that I wouldn't mind either way, I didn't mean that I don't care if they fall into some of the 'black holes' that b&wcat outlined (single mum, depressed, ill, living on the breadline, no support, etc etc etc). Obviously those cases are different, and very sad, but I didn't think that that was what you were asking about.
I took your question to be about how I'd feel, if my dds had had roughly the same life choices that I'd had, but made different decisions from me, iyswim.
I accept that my dds are not me. I would no more be 'disappointed' in my dd if she became a SAHM than I would if she decided to study engineering (I am an Arts graduate!) or to become a plumber (I wish!), or if she got a cat (I'm a 'dog person'), or developed a liking for heavy metal, or whatever. Assuming she was an adult, I'd trust her to make her own decision.
You feel that you are committed to working because you had a strong model in your own mother. I didn't have that. But I am committed to my job (and, I hope, to my dds). I don't deny the influence of the mother figure, but we also have (or invent for ourselves) other role models if necessary.
