I'm sorry you're having a tough time. What is he doing ? does it make him think or will he be kcking his heals up with joy ? What do you think I will say to this?
Ok, I won't leave you in suspense. The answer is: Get. Out. Of. His. Head.
I get that it is hard. By obsessing over what he is doing you are demonstrating that you need some distance from this person. You are too entangled in his life. You need to have your own - something of your own to worry about and do. Get busy.
