Ztawinthropgirl, I like your attitude! I'm glad to see that there are young women who feel the way you do!
I notice that you're in South Carolina -- I think that it varies greatly by region whether women are looked down upon for working or for not having kids. I've lived most of my life in the Chicago area, and from what I've seen, I don't think that, in general, most people have a problem with women who have kids and work. I never got any slack for not wanting to have kids, nor did I ever feel any societal pressure to get married. Marriage and kids seem to be emphasized more in certain areas of the country.
The "you'll become lonely and bitter" thing makes me laugh. There's no guarantee that if you have kids, they'll want to have anything to do with you when you're older. I'd rather be alone than have anyone spending time with me because they feel obligated.
