That's up to you. I don't think it's a big deal, but, at the same time, I think you were warranted in being upset. Whether or not you stay really is a decision of the heart at this point.

Douche move for sure... i don't know... but it says red flag to me when he thinks you would actually do that with your cousin, how on earth could he think you would have a 3 some with family of all people? if i was you id honestly be put off him after that because he would just seem so creepy after and id be scared he would try and hit on my other cousines or friends... that's unacceptable behavior... i'm not even sure myself if he just wants you for your body, id keep an eye on his behavior and if he keeps acting the same way id definitely dump him.
