I think the MC gave you solid advice here FOBD. If you do it the it has to be for the right reasons. Like I have said when I did it I was prepared to hang up the phone. Honestly I don't think right now you are ready to walk away.
Checking to see where we are right now I don't think it is a good idea.
I can save you the trouble and give you her answer if you ask her.
If you do make contact make it about the apology and nothing else. Prepare for nothing and prepare to receive her wrath.
Doesn't matter either way, if you truly apologize then it doesn't matter her reaction
