Per day? Should I start by the hour?
My wife never brings her boyfriends to our home as we want to be discreet. Instead, she goes to their place or sometimes she will get a hotel room. One time she got a hotel room for 2 nights. The first night was for her and her boyfriend and the second night was for her and I. Having her in the same bed was an incredible turn on for me.
Even when your wife first started falling in love with him, she thought her feelings of love for you would remain strong -- but she was wrong. She long ago stopped thinking of you as a real man, and now she only thinks of you as a friend. And yet -- you love her now at least as much, and probably more, than you ever have before. You just pray that there will continue to be some place for you in her world.
