Thats proves that some men are not worth a reals woman love, but intead a dispensable girl that will play around with them

I don't completely agree with this. I think when many people think of jealousy they think only in the extremes. Like constantly thinking your partner is going to cheat or leave you and being paranoid and freaking out when they even speak to another person (of the sex they are into) even if in the most platonic way possible. Or refusing to let them be around certain people even though they give you no reason to doubt them JUST BECAUSE you are worried something 'might' happen. Being controlling because of jealousy is a bad thing. But to say jealousy never happens if you're secure with yourself? I think anyone who says they have never been jealous are either lying or don't understand what jealousy really is. Jealousy IS a feeling plain and simple. It is either negative NOR positive. It's is your REACTION to that feeling of jealousy that is. Still don't get it? Ok lets say you're madly in love with your significant other. You trust them and don't doubt their loyalty to you. But you see a really good looking, charming and obviously funny guy or girl talking to them and really cracking them up. You DON'T doubt your partner but still a small part of you thinks 'What if? Hey maybe this person could be better for them?' But you really love them and you don't want to lose them. You feel uneasy. Now you could let this uneasy feeling go out of hand and become irrational to the point of trying to control your partner. Or you could use that feeling (which is jealousy!) to be the best possible partner you can be. Yes jealousy can be good because it can make us try harder. And after all the effect if they STILL leave you for someone else? Well at least you can say you tried your best. You didn't just watch them talking and laughing with someone else without even bothering to try to improve your relationship. And every relationship could use improving.

I think that sometimes women like to use jealousy as a weapon to get attention from their partners...if he doesn't give you the quality time you crave then you think making him jealous will do the trick!!!
