Just found out about cheating husband yesterday.
First, see a lawyer immediately.
in situations like this honesty is the best policy. my personal opinion is yes, the other womans husband should be told. i have read many stories on this site in which the other woman is not honest with her partner, some even go so far as to try to keep the affair going.
please understand this, i am a betrayed wife. i will now explain something to you that will be hard to hear. most men, will lie, lie, lie. yes, even though you have confronted him, it is as if they are just not willling to come clean. so please be aware of that. he must understand how his actions have affected you. he must also have and show EMPATHY, that is the ability to put himself in your shoes. he has to get it, has to be aware of the pain he has caused. additionally he needs to be very much aware of the fact that he needs to decide NOW. either i love her and i want to be with her (her meaning YOU) or i do not. he has to know that if it ever happens again GOODBYE> that of course is if you are willing to forgive him this time.
no matter what you decide, i wish you well. i am sorry you are part of our club, it is a club that noone really wants to belong to.
I take it you mean he did cheat, kissed and spent time with the OW.
