Everyone in my situation is in their early to mid-twenties. 

A little background info:

So I am 21 years old and in college working on my teaching degree.  From the ages of 14-18ish my life was chaotic because of situations I put myself in. I was constantly gossiping about people, spreading other people’s secrets, getting way too drunk, victimizing myself when things would go wrong, talking about vulgar things a work to get attention (like going into extreme detail about my sex life to coworkers I barely spoke to), etc. 

When I was 18 and had dropped out of college after graduating 2nd in my class in high school, I realized I didn’t like the person I was becoming and was embarrassed by my actions. So from there it took a lot of mindfulness and practice to be a better person, and although I still sometimes catch myself starting to do my past behaviors, I do genuinely feel like I’m a good person that makes a positive impact on other people’s lives. 

Now to the current situation:

I have a best friend, D, who I’ve been close with since middle school.  She loves having big groups of friends rather than close, individual friends so she always wants me to hang out with her friends.  The problem is, most of her friends act the way I did when I was 18. It was so so hard for me to break those habits so I don’t want those behaviors around me. 

For example, D’s other best friend, H, is constantly flirting with married coworkers and slept with her ex’s brother to make him jealous.  I don’t want to be around H because it frustrates me to hear these stories and I don’t want that kind of toxic energy around me anymore. I figured since I haven’t known her very long (only a few months) it wouldn’t be very damaging to stop the friendship.   D told me I was being very judgmental about situations that don’t affect me at all and can just be funny stories to hear about. 

Another example is with D’s friend A. Long story short, A had a one night stand with a guy, the guy didn’t want a relationship, so she’s been harassing him for the past YEAR, lied about aborting his kid (she was never pregnant), stalks his current girlfriend, creates fake profiles and phone numbers to contact him since he blocks her every time, etc. When he rejects her, she cuts her arm and sends him pictures. I don’t want all that in my life. D says I shouldn’t take it too seriously since A isn’t hurting me directly. 

So, AITA for judging these people and not wanting to be friends with them?

Tl;dr My best friend has very chaotic (imo) people in her life that I don’t want in mine. Am I too judgmental?
