Dynamics of your congregation and its "elders" are the key. Under the right circumstances six months is possible if it wasn't too scandalous. Other factors might be:
Does your ex continue to attend this hall? If so, expect it might take longer.
Are you generally liked or disliked by the congregation, and especially the elders on your judicial committee?
Some elders are suspicious about DF ones who immediately begin attending all of the meetings. Almost like they should be too ashamed to show their faces. Sometimes it seems to work better if you take a little break, and then start coming back. Particularly if your situation was well known and generated a lot of talk/scandal.
