Frankly, I'm not sure you don't know how you feel about your W's active cheating. I suspect you are lying to yourself. But you know yourself, and I don't.
If you want to change, I suggest you find a good IC to help you change. If that's not something you want to do, I suggest reading about 'co-dependence.'
Life brings a lot of conflict. You can't avoid it. You can only choose how you want to handle it.
Believe me, resolving conflicts is empowering and exhilarating. It's a wonderful way to build a relationship, if you start with the small conflicts - that gives you a chance to learn from low risk, low intensity conflicts.
You can't do that in your current sitch. You'll have to live with her cheating or risk blowing up your M. But you can do that, even if you're scared.
I urge you to read a lot here, starting with https://www.survivinginfidelity.com/healing_library/reconciliation/what-every-wayward-spouse-needs-to-know.asp?
That's in the 'Healing Library.' I recommend looking around in that area of SI, and I also suggest reading about 'the simplified 180.'
Consider what you've read in response to your thread and the material I've suggested and post again.
We can help if you want to change your life. If you want to stay M to an actively cheating W, we're probably not the best forum for you - but you I think you will remain welcome if you use us as a learning reference in any case.
I wish you the best.
Oh, yeah, one of the universal truths, I think, is, 'You can't nice him/her back into your M.'
