Haven't posted here in a long time but am a big fan of Starsky. Unfortunately the hardest thing for you right now is to realize there's *nothing* you can actively do that will change what she's going to do. Nothing.
You need to accept that, process it, surrender to it. That is the hardest part of all of this, the situation, in terms of what she does, cannot be changed by you. It's too late for that now.
If you want to reconcile, you're in a waiting game, and the only course of action that leads to reconciliation, IMO, is emotional distance and not actively trying to fix *anything* between you because that ship has sailed.
You need to focus on you, being the best man you can be, and taking your attention 100% off of her. Do not be her friend, do not be her safety net, do not engage with her at all beyond the minimum you can manage to co-parent. That's it. Get her out of the house as soon as possible, co-habitation will make things worse.
Does that sound like horrible advice? Is it scary? Are you convinced that certainly it doesn't apply to you?
That's all normal. Everyone feels like their situation is unique, and there must be some answer, some solution they just haven't discovered that is within their control. There isn't. You don't have an option that doesn't suck. You have to pick the least sucky option of all the sucky options you have and learn to accept that. The option that [censored] the least is protecting yourself by giving yourself emotional space.
Distance from her emotionally, but be happy, upbeat, successful and positive on your own. Fake it until you make it. That is quite literally all you can do, and that, my friend, is a very bitter pill to swallow.
Like probably most people here I went through this myself. I did reconcile and had another 3 years post-affair before she cheated again and I was done.
Although it's impossible for you to see at the time, this is 100% survivable no matter how it goes. I've been happier divorced than I was for years being married. I 100% believe in marriage, and I miss the feeling and comfort of "being married" but I do not miss my ex at all, and her behavior should not have been tolerated for as long as it was. At the time I couldn't see it, I thought she was the most wonderful woman ever, and that certainly I could fix this. I was wrong on both counts.
This is the value of hind sight, and unfortunately for most people, you can't absorb it until you're ready. Like the song by "The Faces" says "you have to learn, just like me, and that's the hardest way"
