Trumpet is right Free. I'm so sorry for the recent discovery of OM - that's painful - one of the most painful things we ever get to experience.
However, feeling that pain doesn't make this the right time to make big decisions. You feel like this today, but you may feel differently in a week's or a month's time.
There is nothing to lose by dropping the rope - but please don't file for D in haste. Many R's can and do survive infidelity. It isn't easy for sure, but it can be done.
Maybe tell yourself - I will do nothing this month and will start working through the pain. Then I will review and see where I'm at.
Remember, we don't get to control what others are doing, but our reaction is ours to own. Make sure your reaction is one that, years down the line, you will feel at peace with.
Take care my friend xx
