Ok, even though there were many posters who had no issue with the OP.
After a woman has engaged in an affair relationship with a man and his DW DC have been incredibly hurt, does the woman who was the third party in the said relationship at any point in the future regret her actions?
If she does regret her actions or feel guilt or remorse, is it because she got hurt? He didn't leave?, because he has now cheated? He treats her badly? or because she now wishes she had not hurt the DW and DC. If the relationship lasted, does the woman worry he will cheat?
Or like IME, is she happy and feels it was worth it?
The third party in my relationship informed me she felt her DC (one DC from previous relationship) was more entitled to my DC's father than they were as during the affair my XH had done a lot for her DC. Her reasoning was that if my XH left her, her DC would not see him again as my XH was not her DC's natural parent.
I did not want to involve my own experience as I wanted to hear the reasoning of others.
IMO, I'm in the camp of I feel both the spouse and the affair partner are equally to blame. My reasoning is that, in law, assisting a 'wrong' is also a 'wrong' e.g. assisting a crime. But, these are merely my opinions, I'm interested in everybody's opinions.
