Wow!! Talk about a rollercoaster of emotions!! Your H doesn't seem to know if he is coming or going. I think it might be out of guilt. My H was the same way after 'the bomb' I was a mean nasty B&^%^ and told him that I wanted him out and that he was no longer allowed in my bed. That week he made me dinner and packed me lunch for work. I believe he may have felt guilty and tried to act like nothing was wrong. Trust me now I wish I acted differently and hadn't pushed him away.
I think that it is a good idea for you to stay at your friends house for a few days and clear your head. You do not want to try to make any big decisions now while you are emotional. Take the time with your friend to cry and let out your emotions.
Hang in there. Ali is right you never know what the next few months can bring. As this is all unexpected things changing for the best can be unexpected too.
