Seems like the "ILY's" were not so true. If she loved you she wouldn't have gone back to her affair. I'm glad you didn't say ILY2.
After all that she has done to you, you have to be perfect? You can't get emotional and make one mistake or it's back to OM? Give me a break. You deserve better and you'll have it, one way or another.
I didn't even do anything "wrong" and my W went back, more than once. It's not your fault. She made choices.

It is not things that bother us, but the stories we tell ourselves about things.
