Here's what I think about people who say this: -some people are severely lonely (emotionally disturbed guys with low self-esteem) and think that other people (sad, damaged, vulnerable girls/women) at the end of their rope are probably too desperate to reject them like everyone else does. It still happens. -some people really do mean it, but when faced with the reality of it, realize that dealing with other suicidal, depressed people is far more difficult than they thought and wish that they hadn't offered. -get creeped out/put off for various reasons after the first time someone makes contact with them and surprise surprise, isn't exactly charming-- either tell themselves that the next one may be different or realize that depressed people usually have too hard of a time thinking about anyone but themselves. -are too wrapped up in themselves to really mean it. They think they mean it when they say it, but also privately know that they're just saying it because of some momentary rush of empathy for people they think they should have something in common with, but ultimately don't. Also, may get upset when they realize that they're supposed to listen as well as talk. So yeah, basically my point is that just because someone is depressed, it doesn't mean that they don't suck as much as other people/are somehow more willing to put up with your shit.
