@ChargingBuck Maybe before you charge in with your 'advice' you ought to learn to read.
The OP said in her 1st post she was a fool.
She doesn't needs 100s of anon keyboard bullies to pile in and say it again.
It is quite believable that some marriages are over in all but name.
You see the reverse scenario here, day after day, where women are crying they have lost their partners to the OW so it is utter *rubbish^ to say they never leave their wives !
So to say men never leave is untrue. Often all they need is to meet another woman and it gives them the push to leave.
Equally, there are many women here posting that their marriages are dead and yes, they have met a man and want to end their marriage now.
Stop pretending this doesn't happen.
In RL I know of people who did leave their partners for the affair partner. it happens day in and day out.
And no, they are not serial adulterers.
The OP took what he said at face value.
It was an error.
Humans make them.
Have some compassion.
