I'm going to be very blunt. Very few people are going to try and help you while you are not helping yourself. Either drop your W, get a D, and pursue the OW or Leave OW TOTALLY alone. Do not call, email, have lunch with her, send her "Friendship gifts", NOTHING! You are sending her mixed messages.
There really can be no halfway. You either want to save your M or you don't. Quit hiding behind the MLC label!
