At the very least, OP, avoid him for now. Find excuses to hang out with your other friends or find some new hobbies that you can enjoy on your own. Have your friends who are related to him hang out at your house rather than going to theirs. Whatever you can do to keep him at bay and to take your mind off it, do. It will be tremendously better for your health if you're not always in fear of this.

not okay if it happens in the physical world.
