Faith isn't kidding when he says it can be a really wild ride.
My stepmother and MIL are both bipolar. Untreated. Craziness.
I have a client who is Bipolar as well. Medicated. Still a daily struggle.
Learn about the illness, not just for your W but for your children. Heredity can be a factor.
I would also suggest that you do need to focus on her getting help for it right now, and less on where your M is heading.
I am going to directly suggest that the OW needs to go if you are even in the mindset of considering reconciliation.
For both of your sakes. You won't be able to make a clear decision about your marriage with her in the picture and the longer you keep seeing her, the more attached you may get, which ends up causing more hurt.
If you don't reconcile or choose not to, if OW is the one, she will still be around...
