Pearl, this is why I encourage people to decide AHEAD of time how many (IF any) backslides they're going to accept from the FWAS. Once, but only if self-confessed . . . Once, even if YOU find out . . . twice . . . etc.
Because once it happens, you're too emotional to make good decisions. This way, it just "kicks in," whatever it is.
If he said he was no-contact 3 weeks ago, and instead it was TWO weeks ago, and he's living up to that, then I think you might be overblowing this.
I'm curious, was changing his e-mail address part of the agreed no-contact/transparency plan? Or did he just agree to no-contact, and you guys never DID do a transparency plan?
