Heyo, Wounded Healer.
I don't post very often, but your situation is pretty much exactly mine. In fact mine got "worse" afterword, because in the authenticity we fostered in building our new marriage, she copped to sexual encounters with another 3 men before me, making me 8th out of 9 total.
Now, everyone who has posted so far, including Pacific Blue, has posted some very excellent, and comprehensive items for your consideration, so I won't really rehash their input. Instead, I'll list some high altitude view changes and alterations that I have had and made in my relationship without advising you in yours at all. If you can benefit from them, great. If not, that is simply the nature of human conversation, and there's nothing wrong with that situation, either.
In no particular order:
(I should add for context that I'm a Christian, church of Christ flavored. (The small "c" is deliberate. IYKYK
))
1) The only thing that had been sacred about our marital sex was me, my purity, and innocence. She is the one who held something sacred, pure, and unique, and took a total dump on it. That marriage is dead, and she killed it. That man, really, is dead, and she killed him. We aren't reconciling, we're building a new relationship, with a new man, and everything is different. Everything is different, because everything was ruined. Everything new has its own set of considerations because it must, in light of the new man and him figuring out how to mpnavigate these new waters.
2) The main reason I stayed with her to build a new relationship is convenience, and to avoid damaging our children. I already know from research and conversation that she's a bit of a freak, and I'm an above- average performer. Sex has gone from being bonding and special, to merely something fun to do, finding another woman who has her characteristics and eagerness would be a hassle. And, well, I'm closing in on 50, so that particular fire just doesn't burn as brightly anymore.
3) She isn't my wife anymore, and never really was. That's a biblical term for a woman who has completely joined herself to a man in purity and total dedication. She didn't bring purity to begin with, and she proved her dedication. Now her official status is "concubine." She hates it, but she's accepted it. Note that I changed this status without malice or bitterness, it's just a fact. She is alwats so worried because of FOO issues that I'll abandon her for some young thing. I told her to pay attention to how many times I've abandoned her in the wake of her adultery while considering myself free to do so. She asked if she's exclusive, I told her I have a desire for monogamy, but she has no demand or right to it.
4) She feels like used and damaged goods...but... honestly she was already that to begin with. If anything, I'm already experienced in dealing with that situation. I accepted it 25 years ago because I was young and horny, and that situation hasn't really substantively changed. It sounds harsh, because it is far from the ideal beginning, far from the hopes I originally had, but it's once again simply a fact I have had to come to terms with. She not unique and special. None of us are. She has her unique needs and issues to work on, and it is my obligation and joy, as her husband, to care for them and for her.
5) No one gets to tell me what to make of my situation. I will manage my self and my house with careful consideration and righteousness, and everyone's participation in it is voluntary. I don't make complaints, I make decisions. My power and energies are always in service to others, including myself, and as such are deserving of respect--never demanding, but deserving. Every conflict must be resolved without abuse or neglect towards anyone, including myself. My business in our home are boundaries, order, safety, and an endless supply of love. When I'm doing this, I'm doing it right.
I said I wouldn't advise you, but perhaps you'll see the value in stepping back from focusing on one very narrow aspect of the situation and seeing where and how it fits in the overall context.
All the best,
