I haven't spoke to this former friend for a few years and honestly, she was one of the best friends I ever had. We met when we were 18 and we were housemates for 2 years in a group of 6. From the moment we met, she was so kind and caring towards everybody else.

There were moments where I'd see things irrationally, things that were accidental would be misinterpreted and I'd overreact. When she was kind I was sometimes cold towards her and she became the same way. Then there was a point when I split on her real bad and things were never the same.

It's like she became a different person and the more I think about it, the more I think that's down to the way I treated her. We don't speak anymore and thinking that I may be responsible for permanently changing her like this is honestly worse than the fact we're no longer friends. It's like I took the things I liked about her the most and just took them away from her forever and made her less happy as a result
