6. Not communicating with your lovers. The person, or people, you're seeing should know what's up. Do you like them? Talk. Be honest. You're not responsible for other people's feelings, but you can minimize other people's heartbreak by not lying, cheating, faking, or generally being a jerk. In the best case scenario, you and your lover will part ways because you are incompatible, not because you are too self-centered and immature to respect another human being.
