I recently caught up with a friend after three years. Long story short, he's extremely paranoid. He keeps talking about these two girls-- one being his exgirlfriend, one being some other girl that his family knows well. He's told me how he keeps seeing the ex in different places. For example, two weeks ago we went to a club. He never said anything to me about seeing her at the club on that day, but a few weeks later he's telling me how he saw her there. Which I really doubt. I could tell a few more stories. I would really like to try to get him help, but I'm not sure how to go about it without him turning against me. Any recommendations?
