Too many people are like that, unfortunately. Both friends and lovers. *shrug* I've personally given up believing that people will actually turn out to be 'good' people. I'm pleasantly surprised when people do nice things, but there's no point in expecting them to do the right thing.

I'm hoping that it was just bad timing on his behalf. I think it's despicable to leave somebody because of illness (mental or physical) but, well, we do have no fault divorce for a reason. Sometimes it just doesn't work out.
