Is it wrong what i did?

i would b upset specially when he still pursued her after u asked him to stop. she's not a true friend to him if she's gonna flirt with him. shes a manipulator. all her guy friends are potention f* buddies in her eyes. I would b worried too if i were you. Have you ever asked him if he would rather be with her than yourself? I know its a hard question to ask but if u want him to be truely happy, it may end up losing ur relationship but he'd b happy. (or at least realize what he lost which is u)
