This is a confusing situation at all. You see people, think things are going well, and suddenly leave without leaving any traces. For some time you think he will die or let go, but you know that his activities took place on his Facebook page. He must suddenly decide that he does not want to see you again and try to understand why.
After all, you don’t know why, and there is no way to know for sure. Honestly, your role as a detective will be a waste of time. You do not need to experience this torture. It doesn’t matter why he disappeared or broke the back of a camel.
The big problem here is the emotional state.
They are confusing, worried and annoying. They break the brain and try to determine when everything is wrong. They explore all possibilities.
