W: I'm sure you've heard, but if you haven't, I met your new girl. She seems really sweet. W: She did say you message her a lot and that you need to maybe tone it back a little. Just letting you know so you don't push her away. Play it cool."
betterm,
You know those people that only read (or listen) to part of what you're saying and then they jump to a conclusion without listening to the whole story? Well, that would be me. Although, after jumping to my conclusion, I reread what you wrote and decided that I was wrong.
I read the texts that your wife sent (the quote above) about meeting your new girl. It sounds just like something someone with dissociative identity disorder (DID) would say. DID is multiple personalities. A person with DID will have internal conversations with the alternative personalities (alters) as if they are a completely separate person (for someone with DID each alter is a different person). So, the text messages your wife sent sound very much like two "insiders" are at work. The alter you had the deep conversation with the other day would have been telling the alter that sent you the texts that you should "tone-down" your approach.
However, after rereading you post, I understood that there was confusion between the waitress and the two groups (your wife's group and your brother's group). Oh well, I thought I had her pegged as DID, but alas...
