A Blog Called Everything

Bellow is an excerpt from from this article. I highly recommend you read the whole thing.

Our society is addicted to three core beliefs about relationships that are almost guaranteed to create jealousy even in the most well-adjusted people. Most of us have absorbed these beliefs without even realizing it. Identifying and dismantling these beliefs in our “heart of hearts” is the single most effective way to short-circuit jealousy. Ask yourself how much of you believes each of these three statements. Is it 90% of yourself that believes them? 50%? Notice which belief is most entrenched in your subconscious mind and which one youíve made the most progress on:

Core Belief #1 If my partner really loved me, (s)he wouldn’t have any desire for a sexual relationship with anyone else.

This belief sees any interest your partner has in anyone else as a direct reflection of how much (s)he loves you. It’s a quantitative view of love which equates the amount of love with the ability to be interested in having another partner. When you break it down, this is as absurd as saying that a couple that gives birth to a second child must not love their first child or they couldn’t possibly have any interest in having a second one.

Core Belief #2 If my partner were happy with me, and if I were a good partner/spouse/lover/etc., my partner would be so satisfied that (s)he wouldn’t want to get involved with anyone else.

This belief is even more insidious. With the first belief you can at least blame it on your partner for not loving you enough. This belief says that if your partner is interested in someone else, itís your fault for not being the perfect lover or spouse and your relationship must be a failure. If you truly believe that your lover could only be interested in another partner because you’re inadequate, you can see how that will generate jealousy big time!

Core Belief #3 It’s just not possible to love more than one person at the same time

This belief is built on the “scarcity economy of love”, the belief that love is a finite resource, there is only so much to go around, and there is never enough. Therefore, if my partner gives any of her or his love to anyone else, that necessarily means that there’s less for me. Because most people already feel there are some areas in their relationship where they are not getting enough of something (time, love, affection, sex, support, commitment) they are fearful that they will receive even less if their partner gets involved with additional partners.
