answer:There are a lot of platitudes (better now than later, etc.). But I think you’re on the right track in suggesting that you want to help him see helping her wasn’t a waste of time. He was there for her when she needed him the most. He may very well be the reason she’s alive today. That makes him incredibly important in her life, and should be proof to himself that he’s fundamentally a good person. Regardless of how it turns out, it’s rare that we get the opportunity to find out that, when the chips are down, we actually will step up to the plate. I wouldn’t say it this way, but it’s kind of a blessing…I would be a little more sure of myself in the end, and know that I had the capacity to “be a man” when the time came for it. And it doesn’t matter that he ended up making “the wrong choice” in a girlfriend. People in general can be fickle, and investing in them means risk at all times. Again, the one thing he can take away is that he is not, like most people, fickle. It’s nice to know that you’re a catch.
