Honestly, don't be terrified of him, instead picture him as the little "child" he really is. He is acting like a child bully with you, don't let that child bully have any control over you. If he chooses to not talk to you? So be it, don't beg and plead or even show fear or cower, that gives that child bully power and he doesn't deserve to have that power over you

Do not buy into that feeling, it's a lie, you are NOT LESS THAN HIM.
