Relationship Connection: My best friend had an affair with my wife and still wants to be friends
Having an affair with my friends wife...
End this sooner rather than later, and hope nobody finds out, because if they do, nobody will want to have anything to do with you, you will probably have to move far away where nobody knows you.
Bottom line though, it all depends on the priority of you and of her to keep the marriage more than anything else because you both want to he ther in the marriage.
I made a second pass thru the text to remove anything which did not help describe the situation.
