She is all in for Lucas -- she has put all her cards on the table.
I find it interesting that one of JH's most recent FB posts is a meme stating "The ugliest thing that I have ever seen is a human being without compassion." Who deserves HIS compassion right now? Not his sprung live-in girlfriend. As far as I'm concerned, she's been sheltered, more-or-less on vacation from the realities of Lucas' disappearance.
Personally, coming from a family with a history of mental illness (something JO has owned), I understand her.
So many times in these cases, people ask why parents don't admit the inability to handle their children and "do what's best" for them.
People judge her behavior, not realizing that distraction and self-medicating can be expected -- assumptions are made. People do what they think will help them survive and cope. I cannot imagine being in Jamie's shoes, trying to cope.
Jamie did something that we ask of parents -- she recognized he would be better under other full time care, even if that meant dealing with the pain of missing him. She was willing to face federal charges for kidnapping across state lines in order to shed light on what was happening to her baby, and she says she will never get over the guilt for not acting on that impulse sooner, that she wasn't able to handle things through the legal channels.
What makes a "good parent"? There are plenty of debates to be had, but I believe Jamie did what we wish all parents would do.
Her interviews show that she doesn't hide or pretend, and she's standing in the eye of the *****storm for the sole purpose of finding her baby and bringing him home. I think she is so brave, and I respect the hell out of her.
