I had a friend of ten years (from 8 years old to 18) lose my number. I didn't want them to, not for a second, but I wasn't a good person and it was probably best for my friend to leave. She doesn't acknowledge when I tell her happy birthday over messenger (and she changed her phone number). I don't know why she doesn't just block me or something, it'd hurt less. If I saw her in a bar, I can almost certainly guarantee she'd pretend I didn't exist. I know I wouldn't have the bravery to approach her. You did, though and you got hurt, but at least you had the courage to try. Regardless, I'm sorry you experienced this.
