text: It is only normal to worry about someone you've been with that long and that you have kids with.  However, this marriage is over, and it is not your job to save him.  The best thing you can probably do for him is to let someone in his family know what is going on and let them try and help him out.  You have enough on your plate trying to do what is best for your kids and for yourself.  You will still need to be sensitive and aware to some degree what is going on in his life for your kids sake but you need to accept that you are not responsible for what he does, he is.
