Get an attorney, as others have suggested, to prepare and send them a letter that states you won't be subject to any of their judicial processes and that you will sue them if they take any congregational, df -ing actions against you.
In hindsight, a 5 month fade that includes moving in with your BF was not a very good idea. Since you call it a fade we can assume you have been sporadically attending meetings, etc. during this time.
If so, you have placed yourself squarely in their crosshairs. Good luck. See an attorney.
