In most cases I've seen on here, as well as my own, where the WAW is a cake eater, there's a reason they're a cake eater. They DO have second thoughts, strong ones. But, you need to not read too heavily into anything like this, because
a) the most you know is "something" about her being "this far into it"
b) what you hear one day can be negated by what you hear the next day
c) this is probably not even what you can consider a STEP in the right direction. My guess is she has had second thoughts all the way along. It's just that you are finally noticing the second thought, either by way of something she has finally broken down and said to her mom, accidentally said to her mom, or indifferently said to her mom, or it could just be a persepctive that has finally dawned on you.
What you can do though is file it in the back of your mind that she probably does have these second thoughts, and therefore, that is additional incentive for you to divorce bust and GAL and improve yourself and do all the things you need to be doing. Doing it for yourself still needs to be the primary, secondary, and tertiary motivators here, but it's not like she's running off with the other dude.
Calmly establish her appparent second guessing as fact, and then file it away and prioritize your energy on GAL and improving yourself by doing things you like to do and make you happy.
Also, don't worry, the board hasn't forgotten sbout you. Sometimes certain posts in a thread just don't lend themselves to responses the way other posts do.
