What makes me paranoid a lot of times is not making the observations I need to make. Expecting the information I need to live my life correctly and safely to come to me, that's where the mind wanders. See you are "paranoid" because you don't know. Concern or paranoia?

Can you openly talk about anything and everything with him? He may be perceiving from experience. He may also have trouble turning things over. Like maybe he was suspicious and it was nothing, maybe he isn't learning how to laugh about it.

The very fact that you might mention it just here on the internet. You aren't doing anything wrong but he isn't unjustified by thinking this. He can't "read minds".

I'd say there is a fine line between being actively involved in your world and becoming just too overly suspicious. Sure sometimes I turn ideas over. Got to find what you are looking for. Maybe he's looking for the answer. Could be in his head. Probably is.

One of the best ways to cope with stress is to take a walk. It's where you turn things over and discard them. Have you ever taken a walk with him and talked about these things? He would probably trust you if you did not shun the ideas but rather handled them as they came.

Politicians? Paranoid as hell. Aggressive and bold. Try not to give him too much trash because nobody respects trash. The more you complain about that the worse things will get. He should probably mind his own business and you yours.
