When we love, our desire is focused on one person. We don't want to share this person with others, and that is why we don't like competition. This is in human nature, to defeat, eliminate, even destroy every competitor or rival, because they stand on our way to happiness.
Before we exhume war cleaver, we must be aware that competition is not the main problem. If you have problem in relation, you can't blame other people, because your partner is the one who is with you. You sleep, eat and share life with him or her, not with others, so if something went wrong, discuss that with owner of your heart.
Many women think wrong that problems will disappear if they get rid of their opponents. Yes, that Sheila bitch wanted to steal my husband, but if i kick her ass , we will be happy. Now you get rid of Sheila, Rebecca, Annie and all those trash, but your partner is still cheating you? If you saw movie "The other women" with Cameron Diaz and Leslie Mann, you will get the point about unfaithful partner. Such person don't care for anyone, just for yourself.
What kind of competition can stand on way of our happiness in love?
Ex partner. That girlfriend or boyfriend are still here, maybe in our neighborhood, but you meet them and every time you see person, something stuck in your throat. Why they are still alive?
Best friends. Yes he told you that Mabel is his colleague from work, and that Nadine is his friend from high school, but you still don't believe him, because he share messages with them , he drink coffee with them and you feel that they steal his attention from you.
Fictional person. Your partner maybe joke with you how he dream about perfect women, but every time you see example of his standards, you will feel as shit. That is matter of your self confidence.
What are the most stupid things you can do, when you afraid of rivarly?
Send sms or emails to your rival.
Gossip them around.
Try to wait them in ambush and beat them.
Accuse them that they involve in your relation, even they have no idea about this.
Of course, sometimes you can have right, that someone really want to invade in your privacy. That woman really want to seduce your husband or that man wants to sleep with your girlfriend.
What will you do?
Talk with your partner and check the facts.
Deal with your partner together, how to stay away from that person.
Tell your partner that you feel unpleasant, that you are concerned. If he cares, he will stop negative emotions by his actions.
Relation is based on mutual feelings, harmony and agreement. When you two are together and your actions are mutual, nobody can stand on your way. This moment when something happens behind your back, something went wrong. This is alarm call. It is not invitation that you must kill other woman, this is moment when you need to talk with your partner. If he doesn't care, this relation is dead.
