Bright, If you open a FB account, do it for you and not to "spoil" your h's happy façade. The reason I am saying this is that your h is in his own little world and he may or may not look at anything that you post. Also, what you post may give him something to think about, but it will not spoil the life and "happy façade" he's got going on. It might encourage him to compete w/you on the fun things you do and the places you go. Keep in mind, they have this competitiveness about them and if you say you have gone to such and such a place, they will have to do one better.
Will you invite him to be a friend? How do you plan to let him know you have a FB account?
Again, if you want to open an account w/FB, do it for yourself. Your account will not change his perspective on life right now, but it may make him curious to see what you are doing.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
