I know only too well the place that repeated lies and cover-ups can send you. (Check out my sordid tale, or at least the little summary on page 1)
Even AFTER bomb #3, I discovered a "chat friend" that my H tried to cover up....right after "exposing all" and promising "no more lies" AGAIN.
His explanation? (after the panic attack subsided)...he just SOOOO wanted "all of that" to be behind us, and was petrified that I'd take it as "the last straw" and end our M, that he panicked and lied.
Jethro is right...look at what is happening NOW. I know intellecutally that my H could be lying his A$$ off every day, he could be having another A...but my GUT tells me it isn't so. His ACTIONS tell me he's remorseful, and really working on our M. Go with that!
