I don't think I have a lot of genuine advice to add, other than to say, from my own personal experience ... every situation is individual and unique (so it is best to try not to generalize); though I know that this is easier said than done - when you've been burned. Believe me! In other words, each person and scenario, no matter how analogous to what has happened in the past, is not the same (necessarily). And so, despite what your 'gut' might tell you, or say--when it comes to the topic of suicide, we can sometimes be really downright wrong (about how another "feels," about it...)
Give you an example: when I'd tried to die about a dozen years or so ago. I had two very close friends; whom I'd been in regular contact/or- touch with, multiple times on the daily. When i was going into the . . what I'd thought was going to be the / or my --"end," I figured I had a pretty good idea of how the two were going to handle it (just based on all I knew of them). When I survived: boy, did the exact opposite (reaction) end up happening! Meaning the one I thought would be there for me & etc., essentially ditched & left for Life. And the other became like a soulmate of sorts. Very strange at first, and somewhat of a rude awakening.
And now that I'm typing all this out and saying it to you: I sort of realize that this is more of an isolated event - & not necessarily exactly what I was speaking of above (which was more in an overall generalized sense). But hopefully the meaning, or idea of the message has been conveyed.
