Im gonna take the other side of this argument. There is nothing wrong with Jealosy in a realationship as long as it is justified and moderated. When I see an unknown phone number in my g/f'* cell then I dont see any problem with asking her who it is. And if she cant answer then theres a problem. I trust my g/f and she trusts me but that doesnt mean that when something strage happens we overlook it. Jealousy and distrust is natural and normal as long as its controlled.
