It's all very "high school", like they think they're the cool group or the Mean Girls and you're the outcast nerd. I left that when I graduated HS in 1979 and tend to stay away from any person or group who still hangs onto that juvenile behaviour.
By going back, they'll smugly think you're "coming crawling back" to them because you believe it's the troof, thereby pumping up their already delusionally grand opinion of themselves & their cult. They're not worth knowing or wasting your time on. Best way to get back at them is to make a successful, happy life for yourself.
