What should I think (a question about men)?

hello listen i think its obvious that he like you but i also think that his cousin might have told him to back off cause he (cousin ) likes you and may be that's why he s acting arrogantly listen my advice to you is if u really do like him just go and tell it directly before u get into messy situations and tell him how you feel about his cousin and make it fast before it s too late all the best :)
