Think in Breaking Bad the motive, at least the initial one, is not to abandon the family but make sure when he dies the family will be all right money wise. He was diagnosed with cancer, he does not have a good job. Cooking meth will give loads of money.
Of course he lies, he become a drug dealer. He is going to die and wants to keep is image clean as far as his family is concerned. I get him. Some people don’t like to tell they have a terminal illness, not event to the spouse. And of course he lies about his disappearances.
In Breaking Bad I only see a guy that was caught by surprise with bad news and is trying to leave is family well off when he dies and sees no point in tell them what he has choose to do. Given what he has choose to do of course he lies. It is understandable. It may bother you Limitless, but I think it makes sense that he lies and behaves the way he does.
