Since jealousy is as natural as happiness and anger, I beleive that it can be a sign that it is either the wrong time in your life for the relationship, or that the person isn\'t right for you.
The reason I say this is; if you were in a relationship where your feelings were always anger or sadness, you\'d leave it. I beleive Jealousy is no different, and that when you meet that person where there is almost instant full trust, then you know you\'ve found the right person.
I am currently in a situation where I think I may have found that person, but they are currently out of reach... Despite the distance between us, I have never had a single jealous thought, even when she was seeing someone else. The only way I can explain it is finding complete happiness and knowing that everything will come out perfect in the end.
