Hmm, ok. Not judging you one way or the other- so please don't take it that way. Just something to think on- and don't answer it here- but I understand you are coming back for your SIL. If that doesn't come to pass, what is there to finish and why? Just something to think on...not a judgment in any way.
Df status is a meaningless status, except to JWs who believe in the org- and sadly to those victimized by it. I am not telling you what to do...at all. Just giving you something to evaluate- if you want to.
