Maybe it isn’t so bad? Maybe it is “just” an emotional affair?!
For me, knowing my Cheater had a physical affair was more traumatic than dealing with an emotional affair. So, I minimized what I knew was the case from evidence until the truth was unavoidable.
The truth became unavoidable when she coped to committing adultery.
It is more likely what you know is merely the tip of the iceberg of sinful nastiness. I discovered this was true in my case.
Honestly, I probably will never know the true depth of that nasty sin iceberg. That is a mercy.
While not helpful in the long run, it is understandable to attempt to minimize what you know is true in your gut. This is why you need solid friends who will tell you the ugly truth. Your Cheater is counting on you staying stuck and giving them the benefit of the doubt.
