Well, then, let me give you one other suggestion that might help you take this less personally.
Replace the words "other woman" with "crystal meth".
He was at the bar and excited that he met someone that had some crystal meth. He wanted to do some crystal meth but he didn't get the chance. He is now convinced crystal meth will make him happy and is talking to his friends about crystal meth.
OK, now let's look at that...does that have anything to do with you? Is meth more attractive or desirable? Of course not.
Bottom line, he is in pain and is desperately grasping at things he thinks will make him feel differently. I hope this helps protect what's left of your worth. All types of people become addicts, it doesn't mean their spouse was inferior. Hang in.
