What did he say ... he was very put-out by it, and not happy at all. In fact, he caught OW in a lie about it, which is how he found out. Of course, he would have found out about it through me anything when I saw the email. (He thought it was funny that he caught her in a lie.)

He said Thursday night they had a bad argument. I didn't get the specifics but she must have been pressuring him for a decision. She'd been drinking, which is why she sent the email.

She called him Friday morning, and said she needed the receipt and that it was in his van. She was polite, but then hung up on him. He looked for it but didn't see it at that time. So he called back to let her know he couldn't find it. She then stated that I must have found it. He wanted to know why I would have it. That's when she admitted she sent the email. She swears she was not in his truck that night but he says it's the only way the receipt could have gotten where it was (he did find it).

Again, he was not happy about it. He said she was making threats (about letting me know stuff) and he didn't like that. He then said something which totally pizzed me off - he told her that was "no way to build a relationship."

We didn't talk too much more about it. Between the knowledge that he had slept with her again, and the this is "no way to build a relationship" comment, I was done! He knew I was really angry, and hurt. I told him the fact that he could be considering living with such a person, over me, was enough to make me walk away. Talk about a slap in the face.

He did apologize, and seemed regretful. After I gave him my piece of mind, he sort of sulked for the rest of the weekend. But he wasn't so pizzed at her that it didn't stop him from seeing her the next day! But I really think he is just trying to keep things civil with her because he has to ... I think.

Since then, things have been quiet. He left his phones out last night and they never even rang.

I sure hope you're right that she is digging her own grave. I think so, too, but I'm not betting on it until I see firm evidence that he is off the fence and the fog is entirely dissipated.
