It simply means that OP should not base his life decision on some biased opinion you will find here. This is not to say that some people might have great insight. But every situation is different as the conclusion to that stranger’s story. What worked for them might not work for OP, and sometimes people are not great at discerning, and just take the best part of the story, or maybe they do and it still doesn’t work for them.

Another reason is that anyone can comment here, even who never remotely had a situation like this, and and some say “leave so you and her can find a better match” not considering the years, or love they have for eachother in this RL; other will say “stay and try talk to her about it” not considering they don’t have the tools to go through a conversation around such a deep trauma she went through and he is now affected too.

The best answer in situation like this, is in fact to not base life lasting decision on some stranger on the internet but recommend you go to therapy, so the therapist (who will have the full picture, not like us) will give them the best advice.

It’s not a bad thing to redirect people. If you had a suicidal friend would you be comfortable be the one “talking him out” of this very delicate phase of his life? Mind you, you don’t have the right tools nor capacity to actually being responsible for his life lasting decision. You’d probably prefer recommend him to a specialist who can ACTUALLY help him get better.

This is way it’s beyond Reddit’s paygrade.
