Any emotions is normal. It's how we choose to react on those emotions that become positive or negative. I like to think of emotions as indicators of our emotional well-being. If I feel jealous, it indicates to me that I need to explore inside myself as to why I am feeling that way. I know it is not always my partner/s' fault that I feeling jealous. Sometimes, I am struggling with something internally, or I have an unmet need that I have not voiced properly. Other times, my jealousy is based on the relationship I do or do not have with my partner's partner. If my relationship with Jadez and Antony is going well, then I do not feel jealous when they spend time together. However, when my relationship with either of them is lacking, then jealousy will rear its ugly head.
However, I do agree that our society tends to see jealousy more positively than it should. It definitely never feels good. In fact, I've heard of men and women alike who find it funny to make their partners jealous because to them it indicts "true" love. I think this is rubbish, of course. True love would not try to provoke jealousy purposefully because it is extremely painful to the bearer. I work really hard to diminish and may be even totally remove my jealousy one day. Is it possible? I do not know. I know there are some people who say they never feel jealous, but I do not know if they are truly being honest with themselves or me for that matter.
Any other thoughts?
