Oh, dug... There are major trust issues in your M, and I understand why. I'm sorry it's been so tough.
Whatever happened with the polygraph? Have you resolved the suspicion of the recent OW?
Given the history of your sitch and your recent thread about the discovery of a new OW, I am concerned about the foundation of your M. IOW, I think we have to hash out some things before we talk more about flirting and initiating and sexual performance.
So, what is going on? Do you suspect that he is involved with an OW?
