I am with anvil!
You seriously expect your A to back YOU up against his mother...
that ain't gonna happen.
You, my friend are in the plumbing dept looking for that fresh baked bread!
been there, done that...
You don't have to listen. As anvil said. You can choose not to read emails, delete them. You can choose to not answer the phone. Delete the messages. You can CHOOSE a better way.
You know she's nuts, she has an alcoholic for a child....just like the rest of us...she is sick too. Feel compassion for her but don't accept her blame.
Just roll on and live your life.
You deserve it.
Keep coming back!
