<human>: Could you distill the essence of the text into 1-3 sentences?

EDIT*** To all those who say I should tell her, how do you think I should go about it? I am really hesitant to mail something and definitely won't go to their home. Would Facebook be ok? I don't know her email address.

I'm not going to try to justify cheating. It happened for a few months. I've been married for 11 years.

Anyway, after a few months, I just couldn't do it anymore and ended things with the other guy. As much as I liked him and would have loved to actually be with him, I knew he had absolutely no intention of ever leaving his marriage. He had been very guarded the whole time I knew him, not telling me personal information until he was sure he could trust me. He went to great lengths to make sure his wife never found out, because he felt like it would ruin his kids' lives (and maybe his professional life, I'm not sure). I, however, knew that the right thing to do was to tell my husband and end my marriage. I know my kids' lives will be much better with two divorced parents who'll actually be happy rather than married parents who are unhappy. Telling my husband was the hardest thing I've ever done, but he deserved to know and deserves to be with someone who won't cheat on him.

So, I kind of feel like I should tell the other guy's wife what we did (I was the first he cheated with, but probably won't be the last). However, I'm very conflicted because I do feel like I built up a level of trust with him and I don't want to look like a crazy person. No matter how much I want to just forget about him and move on, I do still care about him and don't want to hurt him. And selfishly, I don't want him to be mad at me (he would be livid of course).

Is it my place to tell his wife? I know ideally he'd tell her himself, but that will absolutely never happen. Should I just go no contact with him and forget about the whole thing?
<bot>: Cheated. Ended the cheating, told my husband and ended marriage. Other guy will never tell his wife. Is it my place to tell her, or will that make me look crazy?
