Answer:
People show jealousy in a variety of bad manners, for example if someone is jealous about your new shoe they may tell someone that it doesn't look good on you. But jealousy about other peoples relationships is far worse because someone tries to spread false information about the two people in an affair so that so how they break up or fail to be happy that's if they listen to them. A jealous person will compare your relationship to some other people so that you can see what is missing in yours such that you fail to appreciate your relationship. They will spread rumors that are not true in public such that you break up. The jealous person at times wants all that you have and when in their relationship will keep on comparing their own to other peoples relationship. Jealous people also can abuse those in a relationship with words like you are not meant for each other or like i wonder what he sees in that small and short woman. They never accept that good things are happening in your relationship.
