@Yuuki you could try to talk to him again and be open and straight forward, tell him it makes u uncomfortable when he talks to ur bff tho i personally think that you should never ignore the red flags trust me they wont go away or change if you've tried to talk to him multiple times and he still doesn't listen then clearly your not his first priority for him to risk ur relationship like that, if he truly cared he would first think about you and only you and how'd it'll affect you, idk ur relationship but this does seem kind of a red flag dont ignore it but you could try again and talk to him again, like a last chance and of he blows it away again, just break up , your worth more than that
I bi*** about everything
