Dear Mr. Love,
The concept that emotions are often not based upon logical constructs is something I find important to remind myself about.
I applied the concept of accepting illogical notions from my wife yesterday. My wife was ranting and complaining about this and that, and I was patiently listening. At one point she said she wanted me to go get her 3 chicken tacos for dinner. So I just put on my shoes and went to get her dinner. Very rarely do I ever drive to get her a take-out dinner.
I thought of a dozen reasons not to get her take-out, but I just did it because she asked, and it was reasonably easy to do.
A common recommendation in Swining articles is to be considerate of your partner's feelings, and changes in feelings.
It is possible that your woman has thought about switching partners, and now realizes that she prefers being with you exclusively. Maybe she is in love with you and does not want to share you with others. Jealousy is not a purely logical emontion. Jealousy is sometimes difficult to explain to our lover. Maybe difficult for me to understand about myself. Maybe difficult for individuals to be fully in touch with their own feelings about jealousy.
There are some threads and references on Jealousy, if you care to do a search on Sexual Forums.
From the Website Reference thread under General Sex Talk, there is a reference to a site that deals with jealousy issues:
