Liveandlearn - There aren't any magical quick and painless answers to what you want to do. You have someone you are "living" with, don't want to marry necessarily (but don't want to give up "living" with your partner), don't really want to go to all meetings and maybe lie about where you go, etc., etc. etc...but want to get reinstated quickly and painlessly.
No magical ways to get this done, I'm afraid. Figure out what hoops they want you to jump through and do it if you want back in. If you want to live with your sweetie, perhaps move 30 miles away where they won't drop in on you, and commute to meetings. Get creative if you want to do it, but it will not necessarily be quick or painless. It will be pretty tough doing all this work necessary to get back in IMHO.
Best of luck to you as you seek your reinstatement.
