I understand his point of view, long hours of daily shooting can get pretty tiring and he is not a strong guy to begin with, also as I had mentioned in another post too, he did look bored.
Barun had also said he gets bored of things pretty quickly, don't blame him at all, have been in this situation myself and no amount of cajoling by my colleagues made me want to go back. This break will rejuvenate him and bring him back for newer and better entertainment.
Yes, just let him go.
