What are the chances that I would find a good man?

I am bright, i am university educated. Presently I am a stay at home mom thinking about working at home sewing, so i can make money and be there for my 4 children. I am pretty, not super gorgeous but comfortably pretty, i have a great smile. I am very environmentally minded and have been far before it was cool. i strive to use no artificial chemicals. I am very interested in the arts, culture, social evolution, human rights, clean and healthy living, spirituality, i go to a christian church but do believe in evolution and gay rights. I love people, but dislike being pulled down by their unhealthy ways. I love indy music because the artists have more freedom over their sound if they are unsigned. I am outdoorsy, and working towards being more so. I hate drugs, but like to socially drink once in awhile. I think i am a very good woman, and pleasant to be with, but i do have things that work against me in terms of dating. Like i had mentioned, i have 4 kids. One is mentally handicapped, not severely, but will always be more dependent than most and requires a lot of attention and understanding. I have no family i can rely on for help, as most have problems with addictions (hence me hating drugs and being dragged down by unhealthy ways people will not change) I am on the poor side, but am very rich in love, idealism, ability to inspire others. I am very devoted to my children, which is in part why i am poor, because my time with them is more important than what i can give them materially. I will accept other kids from a future partner, but prefer they be younger, i am great with kids. I wonder if i h have a shot at finding romantic happiness, a companion to grow with. Let me know what you think. I am in my late 30's and look real good.
