I agree with everything Wh00h0069 and SilverDemon said.

I am currently in your situation as well - and it drives me insane. I am at a point in my life where I do not want to be with anybody. I LOVE being alone, and I like only having to focus on my goals in life. What irks me the most is when my friends and co-workers tell me that I need a man to support and take care of me. I am 23, work two full time jobs and am supporting myself through medical school without loanss. I think I'm doing pretty well for somebody that "needs" a man to take care of her.

Only you know what's best for you. If you want to be single, stay single. Some people just need to learn that it is very impolite to meddle in the affairs of others.
