Hi there, Its obviously difficult situation in ur position. But since going through a biological change ur self does not really help u in dealing this situation this way. U gotta give him ur faith and be clear about ur thought process with him. He is the only one who can do something about ur worry as far his own health is concerned. Then its not something which he does not want to do. If this is something which he has increased in ur absence den its a problem . he may need professional help dere but u gotta focus on ur priority rite now. Keep on reminding urself he is not on a holiday ...so just focus on 'rite here -rite now'. I hope this helps..but feel free to consult further. Take care.
