As far as I can see, the comments on this article aren't as hateful as they were under that one about how your marriage-is-in-the-best-place-it-has-ever-been. Also, no trolls followed you here in reaction to this article. So it seems to have worked out.
You really needn't doubt whether your work is of publishable quality. You don't have to babysit the comments section either, though wouldn't dream to discourage poly activism; there's not enough of it.
As for the content, well, conflicted impulses are only human, and it's good that you refrained from acting on the less advisable ones.
Looks like you stopped writing a few months back. That's a shame.
