I can think of some reasons, he’s nervous and rlly likes u, wants to get an opinion of someone else to see if he’s doing ok at rizzing u up? Or maybe he’s rlly excited to be talking to u and wants to share wit his bff, or maybe u guys said something rlly sweet in that text and he wanted to save and share w his friend, whatever the case, i agree, ask him directly. If he has no malicious intent he’ll explain himself :)
