A BS in Plan A, has a zero lovebank balance, actually it's negative.
There are no deposits from the WS, only Lovebusters, which are withdrawls.

That is why Plan A is so draining.
This is why we encourage BS's to focus on other aspects in their life, other than the A.
It is consuming and exhausting.

If at some point you need to go to Plan B, which is NC from your WW, you will have to have done a stellar Plan A beforehand.
When a BS enters Plan B, it is to protect their lovebank from any more damage, preserve what is left to fight for the M.

Once Plan B is in motion, the last memories that the WS has of the BS, should be of someone that they realize is the best choice for a marital partner.

Make sense?
This is why it is so important to work on yourself in Plan A, be the best that you can be, it's a win win, (poor use of that word in this situation) no matter the outcome.
