Right now there is no way to tell if you've waited too long. For the past year, I was just hanging on and trying to show that I'd changed, but didn't do the LRT. I'm now trying that, but it was a shock to see one of H's FB friends have a pic of the two of them as her profile pic. That's how I found out about OW just a week or so ago. I'm not sure if I tried too hard, or started detaching too late.
Just keep trying to GAL and follow the LRT. Right now he is trying to go out and see what fun and excitement he's been missing. Maybe it'll all blow over, but you have to keep busy or it will drive you crazy. I know, because I've been waking up at 3am for the past week, wondering where I've gone wrong.
