There are no hard and fast rules to dating, but here are some tips that won't do any harm.
Do let go of the past. It's done. Build yourself a small bridge and get over it. Quit telling your story; it's boring.
Don't jump straight into another relationship. Take some time to adjust; you need to be alone for a while to rediscover who you are.
Do find a balance. Seek love, but don't make it your whole life. Get a hobby. Knit, volunteer. Knit yourself a volunteer.
Do cultivate relationships with other single people; it's depressing being the token singleton in a crowd of couples; like being alone on Noah's Ark.
Don't drink in excess on dates. It's pathetic and leads to arm-gnawing moments of awkwardness later.
Don't come on too strong. It's unnerving, and you're dating, not stalking. Keep the mystery and let things progress naturally.
Don't introduce the person you're seeing to your friends and family too early; it's tempting when you're used to being part of a couple, but is overwhelming.
Do be open; rigid rules about a 'type' may mean you dismiss somebody lovely.
Do maintain your self-respect; go easy with sharing information. There's plenty of time to get to know each other; no early soul-baring. It smacks of desperation.
Don't take it all so seriously. Approach it with a sense of openness and fun. Flirt a bit, enjoy it all, and you'll be infinitely more attractive!
