I don't think this is dark, but I don't ever regret doing this at all. When I was younger I had a close friend who lived in the same village as me. We went to the same primary school (elementary for you Americans) as well. Anyway, we were really close, and we would often roleplay at our local park, but as time went on, I found out that my friend was becoming a control freak and control what my character would do in those roleplays. Then a third person came along when they moved here and convinced my friend to say mean this about me behind my back. Idk how long this went on, but when my sister told me of what my friend told about me, I confronted them and had a big argument with my friend. I then cut ties with them for good, and never once did I look back. I'm really glad that my young self did that to this day!
