I dunno about "correct" per say but I do think that must hurt to ask a girl out, get rejected, and have said girl kill herself. I get that right now her family is hurting more, and saying that you could have "saved her" is ridiculous, but why is he not allowed to be hurt? That's going to be a pretty sizable blow to one's ego for someone to literally rather be dead than be with you. He has to live with that; she's dead so she doesn't have feelings about it. Perhaps not the right time to express the feeling, but then again, this sub is /r/niceguys so it's really more of an anti-man narrative than anything else. Men aren't allowed to have feelings or else they should be killed (see: this thread, people literally calling for this guy's death because he said something tasteless in his hurt state).
