It seems like he is trying to make sure you are still there. Making up convos about non threatening, light hearted things to see if you will still respond. I'm guilty of doing this too. When you're in a crisis situation with someone you've spent a good amount of your life with, you have this inner need to stay in contact. I would almost guarantee you that his messages are driven by anxiety from not speaking with you. Stay light, friendly, detached - if you respond at all. I would try to ignore responding for a time as well. Don't jump at the bait the second he reaches out. Good luck! I know it can be infuriating and confusing all at the same time.
