You must have respect for yourself before you can demand that anyone show it to you. Present yourself and act like a lady and others will treat you the same. Don't accept a man walking all over and using you. People only treat you the way you allow them to.
But don't put too much focus on the things that aren't important either. You're 19, so a guy your age may not have the money to take you to fancy restaurants and shows, etc but it's about him treating you with kindness and respect.
Don't go looking. Find happiness within yourself and the fellas will be drawn to your inner light. Get involved in things you enjoy (sports, clubs, or whatever you like) and then you are more likely to meet people with common interests. Don't rush it; just enjoy life and the right one will come along. You've got plenty of time.
