You're just getting secondary abuse from this moron of a counselor. VH is right, this MC doesn't have a clue about this type of situation. You hit the nail on the head...your H is the one who needs serious help. YOU'RE insecure? Because your husband likes screwing other people?
Narcissistic people are notorious for reeling in therapists too.
YOUR counselor said you have symptoms of PTSD!!!!!! From being emotionally and sexually abused!!! GET AWAY FROM HIM AND THIS MC.
You KNOW in your heart, bunny, that both of them are wrong. TRUST YOUR GUT. Always. Don't get sucked back in to feeling like you "should" want to try. WHY? Why should you?
