@ViolinPin I assure you i am not OP. I can also assure i have never been involved in any extra marital affair. I left an unhappy marriage ( my choice ) on very amicable terms , as always made sure I had my own assets and my financial independence. This meant neither of us needed the other financially which; prevented any bitterness and frustration setting in. My ( now grown ) children are very proud of me thank you and they, me and their father do many things together still. I even maintain a good relationship with my ex mil , who stays with me often. My independence and freedom of choice has given my children a very good understanding of what they can now and should expect in a relationship and that also involves not allowing anyone to become totally financially dependant on you , to the point where it leaves you no choices.
I do have a large number of friends, both men and women , over decades, who are either stuck in truly miserable marriages or, having affairs. It is not my place to judge nor would i ever. I am just being honest that these things happen in life. As i said in pp, friends ( mainly female) simply cannot afford to divorce as they entered into marriage with nothing and half of what they have now is not enough for them to maintain lifestyle's they are now accustomed too. The men i know are primarily concerned about their children and then secondarily the financial liability, not child maint but what their wives could possibly spitefully expect without making any efforts to fully support themselves. In some cases this is unfair as , i have personally seen women weaponise the children and finances out of bitterness. I know of 4 men, over 3 decades, ( life friends with their now ex wives ) who had affairs and left, married their affair partner and decades / years later still very happy together. These however, are men with significant financial resources. Their ex wives were left extremely comfortable with £800k houses all paid for , sch fees, 3 x foreign holidays a yr paid for , income of £5k a month for the rest of their lives, regardless of remarriage. Those "spurned" women very very quickly moved on themselves and also remarried so , I guess money and financial security minimises heartbreak?
The OP is not responsible for her affair partners wife, HE is. We do not know what has led him to seek outside his marriage. As i said before, happily married people do not stray. We do not know what his marriage is. It could be sexless and they are forced to stay because of money or fear of losing his children to weekends or 50/50. That is not a marriage. I am merely being realistic about why people who are effectively stuck, trapped whatever you will , have affairs. I am sorry you find it unpalatable but assure you i myself, left my marriage when i realised i wanted to start a new relationship and yrs before i did so. It took me 2 yrs after divorce before i even met anyone i wanted to be intimate with , so i personally have done this all right and to MN standards.
Not everyone has the luxury of doing things the right way. Op has met this man and they have had a relationship. It happens. To belittle it and berate the OP and make her feel worthless and somehow devoid of morals, is unkind and unhelpful. This is really just gang mentality of others who fear their own husbands or wives leaving. The OP is not the bad guy here.
I stand by my comments, if he makes the OP happy and it suits her, this is not the OP's cross to bear. No one has asked on this thread what the affair partners reason for the affair is. No one has asked why he is so unhappy? Just endless reams of moral judgement and pearl clutching. Everyone just assumes his wife is the poor victim in all this and , in my understanding , there is always a reason why men and women stray in marriages. 2 people in a relationship, both equally responsible for it's breakdown.
The OP and the AP getting all the flack here, we really know nothing about his wife. Be interesting to know why the AP strayed in the first place. His marriage is clearly not happy, there would not be an OP if the AP was living in domestic bliss.
