Dev, Here's what Sandi suggested to me regarding the heart to heart: Your biggest temptation will probably be to discuss the relationship. It only hurts things at this point. Talking will not fix the problem now. Nothing will work to fix the M until she gets OM out of head and life for good. If she tries to talk about R, just tell her that when she ends the A, she can talk then. But then add "However. I won't wait forever". If that conversation happens, then don't tell her anymore. When or if she brings up the R, you hold your hand up in the "stop" position and tell her that unless the A has ended, there is nothing more to discuss. When she does end the A, and she goes through the withdrawals (which is a subject for another time), then the two of you talk if she is interested and approaches you first. She should be the one to initiate. Kudos to Sandi for this advice. It moved my sitch in a forward way. Still a roller coaster though.
If there is, indeed, still an OM in your sitch, Dev . . .I AB-SO-TIVELY agree with this ^^^ 1000%.
