Nothing good ever comes from someone who is possessive about anything in live. There is a difference between love and possessiveness. Love is something you want to share with the rest of the world, you want that person to be happy and all of his or her wishes to be full filled by you. You want to give that person all of the happiness. Its trust. When you love someone completely you also should trust them also. When you have doubts in your mind then your not fully in love at all. Jealousy is fine everyone has that , but possessive is wrong.
Trusting that your wife, husband, or girlfriend or boyfriend is what makes or breaks a relationship. If your always worried they are cheating on you and have to call them 10 times a day and follow them around and but your hands on them and hurt them, that is not trust and that is not love at all.
Its very normal to be a little jeoulse when you see a pretty girl looking at your husband and you feel insecure and what them to stop. But its another thing if you are already image them in bed and are already together or have been together with out knowing anything.
Possessiveness = insecurity.
Its someone who is his or her own self-esteem is very low about how they can love another human being. They dont have a very good view of there own self and they dont trust themselves. That is why they try to control other people around them
