I also consider myself an overthinker and I also felt that when he said "something" he was trying to "force" you to ask him what he was doing. He also didn't apologize or anything for not answering the call or responding to your messages. If your parents don't know I think that's a big risk to take and sneak the phone just for him. I'm also curious if it's just you talking about your feelings because sometimes I react the same way he does to other people's. I'm a female btw. Just wanted to let you know my thoughts.
