Your boyfriend's cousin's girlfriend, I reckon.
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.
I'm not sure if this will help but does your boyfriend like your cousin? If you have faith in your boyfriend then even if your cousin really DOES like him, you know that your boyfriend won't cheat on you. If he really does cheat on you then all i can say is - you deserve better than that. As to how to tell ... I guess you can talk to your cousin about it? or you try to talk about your boyfriend to your cousin and notice her reactions and expressions.
No. You are not related to the spouse of a cousin, much less the spouse's cousin.
succa!
Will your cousin not be really upset by this? and if so surely its the wrong thig to do? Think about it before you do anything. If you still want him as ur boyfriend you may as well just go up and ask him out, he may prefer you too! Be gentle on letting your cousin know....
You can always tell your cousin you love them. But it is not commen to love your cousin like a girlfriend or boyfriend.
My Boyfriend and my cuusin

Politely ask your cousin what she is doing, and then if that doesn't work, tell her that he is your boyfriend and not hers so she needs to back off and stay away from him.
