When I was younger, yes, or maybe it was infatuation? There was one guy when I was in my early 20's I thought was cheating on me (and he was) and I followed him and felt pathetic and vowed I would never do that again! I used to get crazy jealous but now, over the past 20 or so years, I'm not jealous at all. I think I just cut that part of myself off. Have gone too far the other way.... so yes, I guess so. But I'm not sure it was as much about the person as me.
Can you generally tell if someone is lying to you?
