Cheating seems more tangible then addiction. I say that now because I was never cheated on but there was also a day, many years ago, when I said I would never put up with alcoholism either. HA.
Here is how 'stuck' I was. I used to wish my xah would cheat because then I felt like I could point and say 'See there....see That. That is unforgivable and I'm leaving." I could never figure out what to point at with the alcoholism. I couldn't get a grip on my reasons for wanting to leave, couldn't justify it. I'm so glad I have more clarity now, in hindsight, but I worry because it is scary to think of how I could live in such a cloud of confusion.
