She said she will stay married if she can talk to OM and others. LOL. Completely logical in her mind. And let me guess you take all this responsibility of her, pay bills, love her - while getting into a lifestyle you didn't sign up for. You may catch a disease or have to fathers someone elses child through your own wife.
I want to see what Allan A and the others have to say.
CB, what are the financial arrangements in your marriage? Who pays for what?
Interestingly, affairs are fueled by a very strong sense of two things: RESENTMENT, and ENTITLEMENT. You can attack the "entitlement" monster financially, in many cases.
