DH, your situation is similar to mine in some ways, but also different. Your W says she never liked sex, shows no affection for you now, and you are essentially separated though still living in the same house. Similar to me. [except: my W never said "I never liked sex"; it was more that she rarely initiated sex, and it dropped to NEVER in the past 4-5 years. Lots of rejections of my initiations. We had a 10-month spell where we just never ML. Her explanation for this lack of sex was that she was never interested though she always enjoyed it after things got going.]
My W now says she pretended with me for a long time, pretended to love me. She said that she believes "we made a mistake" when we got married (4 kids, 14 yrs ago). That she is no longer willing to push away her feelings. The affair she had was just a symptom of the lack of feelings for me. She is no longer willing to work around her lack of feelings for me.
My W has repeatedly told me I should find another, someone who can please me. This sounds Similar to yours. She has even made specific suggestions about other women. "Why don't you marry X?" She's also said to me, "Anyone else would have left me by now." At first I found this bizarre and scary, but as time goes on I am more comfortable with her saying these things. I take them not as absolute truth but as a reflection of the confusion in her heart. It is a lie that she never loved me, I can look back and I know this to be true. There's a lot of revisionist billsh!t in what she says.
Taking a step back, a person who says these things to the father of her children.... isn't well. She's in serious pain. As I share the details of my story with other people, many people comment that my W seems to have huge self esteem issues. And Surprise! Having an affair and taking an ax to the primary relationship in her life, somehow didn't make her feel self confident or empowered.
I have been served divorce papers, about a month ago, so maybe I'm not the best source of advice for you. But, since that time I have recommitted myself to getting a life; to making the changes I want in myself, FOR MYSELF; to being happy FOR MYSELF; to accepting what IS, rather than wishing for what AIN'T.
Sounds easy, but it isn't and I don't always do what I intend. I am prone to sulking. I often wish for happier times with my family. But I do what I can, I do my best. And I hang with people who support me and my efforts, people who know my situation and support my desire to rebuild my family. I avoid people who advise me to give up, get real, or "face the facts."
And as I ignore "the facts", I see glimmers of hope. She is not actively pursuing the divorce. There's no hurry. The papers are filed, but she appears to be conflicted about following through with it. The times we are together I make as pleasant as I can. She actually kissed me yesterday, on Christmas, the first kiss she offered to me in maybe.... 5 months? WOW! She is looking good, taking care of herself more. We shared a bottle of wine on Christmas eve, with all the kids asleep. This was so intimate and touching!
Like you, I have doubts. I wonder that, after 3 feet of snow falls in Tucson, and she comes to me and says "I want to work on our marriage", will I be interested? Will I have the strength to start the work? How will I find trust within me?
I don't know the answers to these questions, but that's ok. Today, I live with the intention to have a family, and to be someone's best friend and partner. I'd prefer if that someone were my W, the mother of my children. I will cross those other bridges when I get to them. For now I focus not on those bridges, but on enjoying today.
None of this is really direct advice from me to you; it's just me sharing my strength and hope and experience with you as you go through this time.
