Trying, LFL's h was LD from the start. And she did try, very hard, to fix her marriage. I think it's fair to say, in all honesty "I simply can't anymore".
Mind you I'm not at all convinced this is really it. LFL will prolly go back and forth quite a bit on this, given how she feels about keeping her family intact for the kids. But I think her position, right now, as it is, no matter if it changes tomorrow ... is fair. She's honest about where she is. And that deserves a ton of credit.
