Hang in there! Just remember she is not thinking rationally right now. Believe none of what your hear and 50% of what she does. Hopefully, this is about as bleak as it's going to get for you.
I would NOT say you are being a moron for telling her you would help her during the transition. You are showing her love. Helping her during the transition is a much more difficult task than turning your back on her.
If nothing else, DB to save yourself. Don't focus on the end goal of having your W want to come back right now. If she bombed you a year ago and then again just recently, you probably don't want her back again just to have her do it again in the short term. If you DB, possibly she will want to come back, and will never bomb you like that again.
