Ugh this girl might come to my birthday party next month

Though my boyfriend is gonna lay down the law on the specific female... I am always cautious around her. When a Marine on Christmas tried to flirt with me and touch me (keep in mind I have a wonderful man in my life), she told me to wear a bra next time so he wont feel compelled to come unto me again. Ugh. Plus my mum is coming to the party and one wrong move... mummy will tear her apart... UGH.
