Some women just want to be alone, think that their "happiness" is out there somewhere and they're missing it, and some just don't know what they want. Some know what they "want" but go back and forth because they know what they want conflicts with their core values as a person. They may even hate themselves for wanting what they want, don't know why they want it, and still can't change their feelings (yet).
No question do some have another waiting in the wings, but I don't think all do.
1800 texts is a LOT. We all have support people though. I have a cousin (female former WAW herself) that talk to. I checked my records and I was on the phone with her for over 1,000 minutes last month. Looking for support and understanding. Now that your wife doesn't feel like she has you as a "go to" person any more, she is using this guy for that person. (too bad it couldn't be a woman that she is going to)
One guy on here got some good insight from a letter his wife wrote d1adsl5a letter
