I am so confused, not sure what hand I am playing

[Snow White]

Some more advice please wise ones. There seemed to be a point where things seemed slightly "normal" for a few days. Now my husband has returned to behaviour that I see in my self when i am either very anxious or depressed. He is eating very little, and again this morning woke up at 5 am because he couldn't sleep (he works at 11 today, normally trying to get my daughter to stay in bed so he can sleep past 8). Last night he took a bath then when he got out just sat there and stared out the window for about a half hour, same thing when he woke up this morning got a coffee and sat there staring at nothing. So the question is...what do I do, last night I just left the room and watched tv in our bedroom. I don't know if I should be acting as if nothing is wrong and being super happy or I should be cool and let him decide when and if he wants to talk to me.
