Assuming you are right that he is being sincere, why didn't they got through this a long time ago? 15 years in a vegetative state? I can understand that last 3-5 years have been in and out of courts, but why did they wait so long. If you are right, his commitment is noble.

But for all intents and purposes he has tried to move on with his life. He's got the live-in gf and two kids. At some point you'd think he'd want to say "I need to move on."
