Do you have Facebook Jealousy? Researchers recently discovered that for people who are already predetermined to exhibit jealousy, Facebook reinforces that behavior.

Psychologists found that Facebook is a prime place to reconnect with past relationships, and that could be a concern for anyone involved in a current relationship. Facebook friends can develop a sense of intimacy with each other, too, and that could feel threatening.

I've found that Facebook jealousy is not an issue for me, but here's what brings out the green in me: Friends posting pictures of their fun vacations and trips, especially when I haven't taken one in a while. You know, the smiling faces, the posts about getting on a plane and heading somewhere warm and exotic. The couple in their resort wear, raising their wine glasses toward the camera. Gets me every time.

OK, I guess I have Facebook jealousy..in a different form. Perhaps the researchers should give me a call. Or maybe I just need a vacation!
