Jillian, I really think they do take on a different personality and the one that came back is the "real" one. <P>I know my H is polar opposite. He is sooooo different and even says he's "changed". (into what he can't say)<P>From all that I've read here and in books I really think an affair does somewhat the same thing to the body physiologically.as a drug. One of my closest friends H has a very bad drug problem and has said a lot of the same things to her that my H has said to me.<P>Also, S.Harley...told me that the brain has a shut off valve...when doing something so against their moral character...they almost do have to change.<P>In depression (which includes MLC) some say it is almost hormonal.. Plus, depression itself can rewrite history...and an affair is definately a self medicated treatment for depression.<P>Chick's is probably right for most regarding needs being met.... Perhaps life itself becomes like a windshield wiper (and stays that way for conflict avoiders who do not know how to communicate needs)... and the affair and change in personality are part of the grass is greener syndrome.<P>Whatever it is, it is hard to deal with. I think that I can't ever imagine treating my H so heartless...even since this affair. I cannot imagine what I have done to him that has made him want to treat me or the kids this way....<P>I think just discussing your fears with him in a non threatening way might be a good way to start to cope with it. I would love to even be able to have any conversation with my H,,,,but when we start he just becomes that different person and says contridictory things!!! <P>So many people here have experienced the same as you... they can offer great advice!!<p>[This message has been edited by tootrusting (edited July 29, 2000).]
