You are not related to your boyfriend's sister, although you and she may be friends. If you were to marry your boyfriend, she would be your sister-in-law.
NO its not ok to date your sister ex boyfriend that nasty to date your sister ex boyfriend i would never date my sister ex boyfriend and i hope she wont date my ex boyfriend
Absent any other twists... your sister's boyfriend is also your cousin, for example, so that your sister's boyfriend's cousin is your brother or something... it is completely fine to date your sister's boyfriend's cousin if you want to.

Tell the sister that her boyfriend is disrespecting you. She should settle it. Tell the boyfriend that you do not appreciate him disrespecting you. Other than that, there is really nothing you can do.
