毕竟人狗殊途我不怪你

This name suggests the user has experienced a painful separation or difference with someone, possibly a metaphor for an irreconcilable situation ('dog' may symbolize a significant other or a completely different entity). The phrase means that despite the differences and inevitable separations, there is no resentment towards the other.
