There is no need for everyone you know to know all of the details of your marriage and your problems.
I beg to differ on this point... And infidelity experts concurr... leaving an affair alone allows it to escalate more often than not.
BND, this is not the place to "debate" this topic. While sometimes I agree exposure can hurt the goal, this is certainly NOT the way to get the point across. This is down right rude and hurtful.
If you want to "debate" the topic, I would welcome it on your own thread as Allen has already suggested.
