This is really sad to read and indicates a learned lack of trust in intimate relationships and/or with one's own behavior.
My comment was a) a genuine human emotional response followed by b) a factual observation that such a mindset is clearly derived from a lack of trust.
Since your comment didn't do that, I read it as more of a putdown than it sounds like you intended to convey. Commenting on someone else's intimate relationships and psychological state is exceedingly personal territory. Internet users often, unfortunately, step into that as a way of being snide to others (it's even a bit of a trope, though I'm not saying your comment went this far: https://hn.algolia.com/?sort=byDate&type=comment&dateRange=a...). And this becomes much more likely when the context is an ideological battlefield, which gender issues are.
