Dear Steve and Shirley, I’m a 40-something married female and I knew that my husband cheated on me for years and I finally gave him an ultimatum at the end of January.

I met his girlfriend and she was honest about their relationship. She said it was only for the sex and she’d been asking to involve me in their sexcapades.................................
