Is he serious about his new gf or no?

I am sorry but what are you thinking?He wasn't interested in you to make you his gf.He got one and he still wants to keep his relationship with you.How selfish of him!He doesn't want you for long relationship but wants you as a friend with benefit.Next time just limit your friendship.For me he was literally saying you are not good enough to be my gf.So think about it
