well try to show them theres nothing to be jealous about and gradully there learn to trust you and he/shes prolly only possessive because there afraid to lose you but if you know that person will not change you should be careful because jealousy and possesions can make a person stalk you to make sure no guy/girl touches you he/she thinks they own you and nobody can have you they may even try to get rid of a person whom they think may take you away from him/her...i dont know if that was much help but you should think outside the box every now and then
Controlling
Jealousy can be viewed in two ways : being jealous of someone, or being jealous over someone else's interaction with another person (such as a boyfriend) Synonyms for jealous could be envious, covetous, or the slang "green-eyed." A synonym for the second form is "possessive."
The likely word is the adjective "jealous" (envious, or possessive).
Possessive, demandingEnvious
Not necessarily. It could mean she is just possessive and jealous of you and wants to control you.
Jealous
possessive, suspicious, vindictive = gets/becomes/is jealous tantalizes, philanders = makes jealous
If you are with someone else then it really should not matter what your ex thinks either way. If you are trying to make him jealous and just using someone to do so that is wrong and not fair to that person. If your ex is jealous you will know by the way he treats you.
Tell that jealous person that if they really liked you then they would only want you to be happy, and that your girlfriend makes you happy.
It's not really good to try to get someone jealous. It could backfire really bad on you...trust me. But it depends on who you wanna get jealous...if its a boy/girl then just pay no mind to him/her but pay attention to some of his/her closest friends. =]]
Ask them
Yes. In fact is has two 's'es! The possessive of someone is someone's.
