So you know MC is a waste .... why go? IMHO I would cancel or just not show up, if asked why I would tell her no sense going to MC when there is an active 3rd party, when she is TRULY ready to work on the M you will know, she will know, that time is not right now. Going to MC knowing its all for nothing would only harm possible MC down the road when you both are all in and wanting to work on things, otherwise its a "Well we already tried MC and it didn't work out so whats the use" type attitude.
Just my opinion, I would not go ... my time is more valuable than to put up a front that the M is being worked on while she is off with OM till whenever.
