Dear Abby: I have been married 30 years and have raised four children to adulthood. I recently found out my husband has been having an affair with a prostitute from a strip club. He paid all her living expenses and promised to marry her. She was 26 when it started; he is 56. He told her his wife had run away with another man and that he was divorced. When I confronted him, he lied, lied, lied.

He wants to continue living together and pretend nothing happened. He went to counseling and quit. Then he went to a psychiatrist, who diagnosed him with a "mixed personality disorder." He says he wants to make up for his mistake with me, but all the while he was having unprotected sex.

I doubt he'll ever stop lying to me because he always has. I can't spend the rest of my life looking over my shoulder because this has happened before, although not to this extent. He said he just "led a double life" and he doesn't want to do it anymore. He admitted he did it because he never thought he would get caught.
