Love guru Mike Mandel pulls an about-face and reveals the five quickest ways to ruin your relationship. File these tips under domestic don'ts!

1. When in doubt, blame!

It's much more fun than personal growth and is a wonderfully effective way to destabilize your relationship.

2. Always have an out.

Make sure he/she understands how special you are by threatening to leave him/her. An exit door means you'll never have to learn coping skills so you can repeat the same mistakes over and over with multiple partners.

3. Generate heat instead of light.

Insight is less important then freaking out, so feel free to throw gasoline on the fires of disagreement.

4. Choose badly right from the start.

Rush into relationships without giving any thought to your long-term compatibility. A bad beginning will ensure a bad end.

5. Bring back the zombies!

Keep bringing up old arguments from the past and tired, old pet peeves while you're at it. They're great ways to kill a relationship.
