1. Friendship is first. If you can't be friends, then what's the point?
2. Don't date a "fixer-upper". You can't make a person change; the way you meet them is the way they are.
3. Don't date people who are not totally free of their previous relationship or marriage. If they're still involved on any level, then they are not ready to move on.
4. Can you make each other laugh? A good sense of humor goes a long way.
5. Don't ask things of your partner that you wouldn't ask of yourself.
