When I'm in a relationship I never get jealous and I always let the other person do what they want, even if they decide to sleep with someone else. I even tell them I don't mind. What's wrong with me? I'm a friendly and loving person and don't even get upset much about anything.
Now, if your S.O. wanted out of the relationship because he/she wanted to be with someone else, would you then feel jealous or would you not want to lose him/her?
