I apologise in advance that there's a lot of back story to share before I get to my question, but it is all relevant. I'm 44, DH is 42. We have DTs aged 6. Both of us work. We struggled for years to have children (including 2 MMCs) and eventually had IVF which was successful and our twins were born 6 years ago. Our marriage was, I would say, absolutely rock solid and born out of being great friends.
During pregnancy and beyond, our sex life tailed off to the point where it only happened maybe monthly. Our conception troubles took it out of us both, undoubtedly, and the strain of a twin pregnancy plus premature birth plus then having twins...it's hard to feel like it. Being truthful, I was 95% responsible for it tailing off.
We last had sex very nearly 5 years ago. Just after then, I discovered that he was having an affair with a woman at work. I gave him an ultimatum and told him I would take him back if he gave her up and worked on things. I was so shocked, it didn't really sink in at that point quite how serious a betrayal I felt it to be. I was then unfortunately blasé in assuming that was the shock he needed, and was blindsided when 6 months later he actually left me for her. At that point our twins were 2.
We lived apart for 4 months and then at some point the scales fell from his eyes and he came back begging to me. He had finished with her and he loved me and realised that he needed me. I was on my knees emotionally at that point and needed the reassurance and support, plus the children needed their father and it felt like the right/best thing to do. It was applauded by our families too who had been aghast at the affair.
We have not had sex since but have been for marriage guidance after he first returned, and I have separately seen a counsellor to tackle what I feel is a lack of emotional feeling and sex drive in me. I just couldn't get anywhere with either of them, in the sense that I haven't been able to reestablish any contact with my former love for him or wish to have sex. I do feel a big part of my emotional self has been locked away inside me as a result of the multiple stresses and shocks, and I simply can't get at it any more.
I am a very loving mum and I experience love and joy with my children, but not with him and rarely with any other part of life. I would describe our relationship now as friendly but effectively quite neutered, he tries to reach out and touch me/hold hands/rub my leg etc but it irritates and I feel no love beyond friendship. I am so far away from wishing to have sex with him that it's unimaginable that it will happen now.
We have been on holiday all together and while lovely I spent most of it feeling like I simply must tell him now how I feel. I know the story reads like he is an enormous shit and shouldn't expect anything from me, but he was always a lovely person and since that affair ended he reverted to being a kind, thoughtful, supportive partner and I do feel warmth towards him as a friend. So I would like him to have the opportunity to find a person who might love him more fully than me, if he wants it. If he still loves me and can stand the lack of sex then I don't think that's a problem for me to carry on as we are - so long as we both know where we stand. To stay together effectively as friends co-parenting would mean financial stability, the children staying in their current home/school which they love, so much less disruption for them, families needn't know anything about it, we could all get on fine. If he decided he did need a partner in the fuller sense, then I think we could divorce amicably and I feel that's doable as well (with a lot more resistance from family and obviously the children would need help understanding).
I just can't broach the subject with him. I tried and tried to start a conversation on holiday but simply couldn't think how to go about it. It is so blunt to say that I will never want sex with you again. Please can anyone help me figure out what the right thing is to do here, and how to start this conversation. I'm so lost and unable to share with anyone in real life. I am miserable in living untruthfully and being expected to get back to having a libido at any point when I know it won't happen.
