Only you can decide what you want out of this. The longer the A goes on, the harder it will be to break off, but that doesn't mean it can't happen.
You can't stop her, I think you know that. If you want to keep trying, you can hope/pray that she stops it herself. It happens sometimes...sometimes the OM will turn into a jerk or become unattractive and you are the better option then...but that is impossible to predict.
This is tough. A non-DB friend once told me that I need to be able to look inthe mirror and know I gave it 100% so there were no regrets later in life...I took that to heart...it kept me trying for a while longer...
