I feel like it depends on why you stopped being friends. I have two ex-best friends, one we just stopped being friends because of communication issues and I would totally reach out to her, but the other is a very long and completely different story and I probably wouldn’t reach out to her.
Long story very short she essentially iced me out while still calling herself my best friend, would plan stuff I wasn’t invited to in front of me, ignored my texts while responding to other people in gc I was in so I knew she was on her phone, ignored me in group settings, talked shit behind my back, lied to my face, and then blamed it on stress from college applications.
