In a word YES YOU ARE-
all the comments are wonderful, but i hate to be the devil's advocate- but there is no such thing as jw"logic"
while i think you are free to marry whoever you want to AND whenever,
that has nothing to do with those who look to a user guide that is a few thousand years old along with the latest publications
sad to say according to the rules that your mom liveS by you are indeed an adulterer. my suggestion is to mentallly prepare yourself for the worst, just in case she decides to invoke loyalty to the org and god
but since she is already doing questionalbe things according to wt, she may not say or do anything at all
today more and more jw are being lax in how they obey wt rules,
more jw speak and deal with dfed family than ever before today
so your mom may not do anything , but you do need to be prepared just in case
as the Boys Scouts say ALWAYS BE PREPARED
