<human>: For 7 years I have been fortunate enough to maintain a very amicable relationship with my ex-husband.  We have two children together (7 & 9).    I would go so far as to qualify him as my very best friend.  Yet, for the past two years he has been carrying on a relationship with an evil married woman.  He met her on one of these "discrete encounter" websites.  She has since left her husband, and has been living with my ex for 3-4 months and now she's pregnant.   I'm very very sad to learn this news.  Not because I am harboring any feelings towards this man, but because I know this will forever alter the relationship we shared.  I'm sad because even when I've felt wretched about myself, I was always able to feel "special" for having given him his two children. Now some repulsive woman will step in and recreate this with him.  It just makes me feel horrible.  Now I have nine months to listen to my children excitedly anticipate the arrival of their new brother or sister.  I know I can't change the situation.  I know I should just move on.  But how do I handle myself?  I can't escape the feeling that this woman has "won".  That she has succeeded in her efforts to thwart this wonderful relationship we have maintained for years.  Any advice?
