My spouse and I are both the betrayer and the betrayed. How do I handle my betrayal when the affair partner is my husband’s twin sister’s boyfriend? His sister is no longer with my affair partner. She does not know nor does his extended family. It is also a very strong possibility that either myself or my spouse will run into or see the affair partner whenever we visit my husband’s family because he is still friends with my husband’s family. My husband and the affair partner have had a couple of conversations about what has happened so the affair partner is aware that my husband knows.
