Thank you both for your responses. @leafields I appreciate the resources, I have heard about "Not Just Friends" through another sub, who recommended me to this website. I am glad to have found a sort of a community that may understand what I am going through. I never considered that the MC therapist might take his side and shift blame, I can't imagine how horrible that would be.
@Cooley2here I believe you are right, I believe he does need IC before we do MC. As well, I will be doing IC to sort out my feelings before inviting him in to MC.
I confronted my WH last night about the lies and other text messages I stumbled upon within my search, I told him how I was disgusted and embarrassed, that I would be getting tested for STI's. He says he lied to save face and not muddy the waters any more than they already were. He told me that it was only because of his ego and needing validation, that nothing physical ever happened so I did not need to be tested for STI's. I told him I was doing it regardless, because I do not believe nor trust him.
Honestly, it terrifies me to be a single 40 year old woman with a young daughter. We are a blended family, I have 2 adult children who have moved out into their own places and are attending college (mine from a prior relationship), we have a teen son (his from a prior relationship, but I have raised since he was 4 as his mother only sees him once a week), then we have our daughter together.
My first relationship ended due to physical, emotional and financial abuse, and he spent years after trying to ruin my life after I left him. I am so scared of going through that again, or traumatizing my younger children. Not to mention, my step-son would stay with his father, and I worry about leaving him like his mother did. I met my WH while I was going through a horrible custody battle with my ex and my WH came riding in like a knight in shining armor. He made me strong and helped me overcome the abuse. I was so young and wounded with two young children, no career or money. My life was so perfect from the outside looking in. A thriving family, financially sound, WH owns a successful business, I have a career which I worked very hard at and am very proud of. He was a wonderful husband, caring, funny, fun, brought me flowers every Sunday, was affectionate and loving, always kissing and hugging me... constantly telling me how much he loves and appreciates me. I think this is why it is so hard to see him in this new light. I feel like I was fooled, a wounded bird taken and built back up only to be wounded, again, by its savior.
I have a lot of guilt and shame from all of this, I am extremely embarrassed that he has been openly disrespecting me in front of people/friends. I also am very upset with all of the individuals who supported and enabled the poor behavior. I am hurt and angry that no one told me... It was not just one friend, it was many. One of the women was actually his friends fiancé, who I considered a friend. Albeit not a close friend- but nevertheless. She introduced my WH to this woman, and they all spent nights drinking and partying together. Going to the casino together and who knows what else. Being it was only the 4 of them, seems very double date-y to me. Like she facilitated his A. I am also very angry that all of these women knew about me. They knew he was married with a handful of kids...
Logically, I know none of this is my fault- but that doesn't make the feelings go away. I have intrusive thoughts that make me physically ill, nightmares that keep me up at night and cause extreme anxiety. All the while he is acting like nothing happened and gets upset with me when I ask questions and try to make sense of it all, not that it will ever make any sense.
