With the first EA, when I finally figured it out and knew exactly what was going on, I wrote an email that basically said "I know about OM. If you want to drop him then we can work on the M. If not, then this is over and we can both go on." I never sent it because right before I was about to send it, I noticed that she was losing interest in the OM. She broke it off shortly there after (including blocking him from her email account).
Now I wish I had sent the first letter as I was in a better position then to kick her out (was not working full time in another state). None of the base issues were addressed and now she has a new EA with a different OM.
My brother once told me, "Pup, no one ever says, on their death bed, 'I wish I had spent more time at the office, and I wish I had taken LESS risk in my life.' "
