@andrea123,
Give yourself sometime to spend time with more men and women. make friends. Go out to dinner, see a movie, go to parties, get to know yourself and let others get to know you. Live the life of a young person for awhile, resist moving in with a new boyfriend because he says the two of you can live better together than by yourself and you two can get a better place to live. Live within your means, on your own, and you won't have to fight over the microwave and radio later (people my age would fight over the records/albums/stereo.....I think now they fight over ninetendo's or it's newest version)
Avoid negative people, pay attention to positive people. Beware of the passive aggressive. Ignore people who tell you, you're too picky. Just because they compromise, doesn't mean you have to as well. Your life is in front of you, learn to enjoy it.
