What was your sex/physical relationship like before this guy came back into the picture? Because the above sounds to me like her relationship with him is spiking her drive through the roof and you're getting the spillover. Not only is that pretty repulsive, being the virtual equivalent of sloppy seconds (IMHO), will it continue if/when he is *physically* available to her? Is her desire being mostly or solely propped up by her affair? How viable is that, long-term?
This is exactly what I was thinking, and yeah, it's way icky if she's having sex with you, CE, because she's horny from her cyberaffair with him. Why is her behavior acceptable to you? I just don't get it. You don't think you deserve a woman who is committed to you and your marriage, who wants to have sex with you and only you because she desires you? Where's the fight for your marriage and your family? If she is testing you, I'd say you're failing miserably.
