[He feels guilt more then anything..he does know how the other Lan Wangji feels. He's been told as much recently but he still has his reservations...this world likes to play tricks and even if he can connect the dots of what happened on his own world...he's not sure how he can believe anything that happens here.

[Perhaps that is why he feels comfortable being with and talking to this one. The memories are different..the stories flow in different ways. Perhaps his mistakes are not as big. He doesn't know what his future holds but maybe this is why they part ways...because Wei Wuxian makes some unforgivable mistakes that he can't come back from.]
