As disappointing as it is to admit it, some friendships inevitably come to an end, even if those involved can’t imagine that ever happening.
Redditor u/Dry_Reception_622, for instance, fell out with her best friend after three years of living together. To make matters worse, when they first moved in together, the OP didn’t put her friend’s name on the lease, which made going their separate ways not only upsetting, but complicated, too.
