I think it was the most mature decision you could make, although a very hard one. I did the same thing with my WW. I asked her to make a choice between me and OM. Told her that I could not and would not live in an open marriage. She ultimately filed for D but I retained what dignity I had left and am able to move forward with a clear conscience.
