That is funny! Well, I do agree that when boys become jealous they are really cute in a way that they have their softer side but it does not mean that they could not start a war and become some other communists! Girls are pretty cute too when they are jealous. I am a jealous type but I don't wage war, I cool down and try to suppress it and somehow, eventually act as diplomatic as possible. I want my man to be sensitive and feel that I am jealous, too! If everything is really inevitable, maybe world war Nth will definitely takes place.
Of course, both parties should be ready to raise their white flags and surrender about being jealous. Jealousy is just normal and given the right rationale, it's sweet and could also be a means of strengthening the couple's relationship! It's how you deal with it, actually!
