That's shitty. I think there are different levels of friends. Some you just have dinner with and chat small talk. You're okay with seeing them maybe once a month or every two months. Other friendships you build more like a brotherhood or a soul sister and you tell them your deepest secrets and goals and you KNOW you are in safe hands.
Keep him at a distance if you keep him at all. Don't let anyone steal your thunder. It was your job, your satisfaction, your happiness. Not his to ruin. He could've just been happy for you. I'm sorry freddie, you didn't deserve that.
