My heart goes out to you. I know this is hard. I know the unknown is hard.
BUT
Life is precious. Your life is precious. Life can also be very short. You have to take what you have now and make the very best of it. No matter what happens in your situation you will regret wasting these years thinking about the OW and your H.
They simply are not worth it.
At this time, they can no longer rent the space in your head.
Thinking of you....... Trusting
