In Macdoodle's defence, I think Mummee, you really need to review your posting style. A few weeks ago, you posted that "no-one has an affair if they are happy at home" which, as many people will tell you on here, is far from the complex truth of many affairs.
Then this statement, which took my breath away: "Sorry, while i am not suggesting that a couple cannot save their relationship after an affair, i am very sure that the majority of men who do are NOT happy, whether they leave for OW or stay with the wife."
How in God's name do you know that men who leave or stay are not happy?
A few weeks ago, you were also claiming that absolutely nothing happened between you and your DP before he left his wife. Today however, you reveal that: "the "affair bit" (ie him seeing me behind her back) of our relationship lasted barely a month before he left her." You seem to be in denial that just because you didn't have sex, you weren't involved in a relationship with your DP. I imagine that's why his ex-wife is so bitter - and also his daughter.
I'm also very suspicious about men who claim their exes are bitter harridans with no redeeming qualities - but I do think some women are so competitive that they believe all this nonsense and think that they are somehow "better" than the ex-wives. Mummee, you seem to show no compassion for a woman whose marriage broke up - instead in some peculiar way you blame her for this. In reality, marriages are never this simple or one-sided - I don't imagine he was a paragon of virtue either and in the end, he took the coward's way out and ensured he had another woman to go to before he left.
Like others (and Amy, who was brave enough to be truthful about this) I think that many marriages are actually pretty good - that is until someone comes along and offers an alternative. At other times - and often because of life crises like deaths in the family or a newborn - marriages go through a rough patch. I do think that third parties who capitalise on that situation have some guilt to bear. People who offer affairs to a married person who is going through a crisis are actually delivering a death knell to the marriage.
I have a general philosophy on life that has served me pretty well up to now. Anything that has been gained on the back of another's pain is not worth having. I have also noticed throughout my life that people who don't follow this rule tend to suffer their own pain somewhere down the line....
