I agree that it is a hateful act towards another woman, but then I think women can be extremely jealous of other women in general.
I'm sure there will be comments about how ow never think of the wives and it's just about the sex and the love with the men but I don't believe it. To conduct an affair being an ow who fully knows about the wife must have an effect on the affair relationship, to have a love affair that works arround a marriage must bring thoughts of the wife to the ow constantly.
Through arrangements, let downs, even the act of sex, the wife probably goes through their heads, how could it not, you would have to be lobotomised to never think of the ap''s spouse.
I should imagine for some it hurts, for others they will get a huge power thrill, personally I know I couldn't do it, knowingly harming an innocent woman and family would kill all desire, sexually and emotionally.
I have no idea how for some it is a thrill, I could never be took in by some lathario that professed to love me whilst hurtling back to his wife after time together.
I just don't get it at all, are some women so starved of attention, bored, lacking in imagination or life afirming achievements that they consider it a confidence boosting hobby.
I personally can't think of anything worse to give an arsehole of a man a huge ego boost at the expense of a gaslit woman/wife.
Each to their own I suppose.
