@:-) Ah, you forgot an apostophe! (Or used a noun/pronoun with two possible ambiguous references.)
So you you meant,
FlyerTalk has brought people together into primary relationships, even marriage, and has led to the demise of others'.
or
FlyerTalk has brought people together into primary relationships, even marriage, and has led to the demise of other relationships.
Without that important punctuation or reference, instead of referring to the demise of others'
relationships, your ambiguous use of "others" could be (and was) read as refering to
their demise (
"the demise of others"). Particularly in the context of the immediately following sentence in the same paragraph.
We have shared in the joy of births, anniversaries, new jobs, and successes, and commiserated with one another during times of loss, death, and other personal, national and international tragedies.
While I knew there had been deaths and suicides of FlyerTalkers, I had never heard of those deaths being
caused by others amongst us.
I am pleased to learn of your error or ambiguity, because the meaning of your actual words was quite alarming.
