My boyfriends “friend”

Alrighty ladies. I’m gonna go on a rant. So my boyfriend is a super friendly guy so he has a good amount of friends, especially females. I don’t get jealous easily or at all really but this ONE girl is really starting to irritate me. Now before things get misconstrued, he’s not entertaining her but even though she knows he’s in a relationship (she asked both of us), she CONTINUES to touch on him and follows him everywhere she can. I told him how I felt and this is what happened:

Sooo I apologize for the language but in my defense, when I get angry or upset I’m super impulsive. Anyways, she has a boyfriend but still continues to be all over mine!!

I need help because if I say something to her I’ll say something to make her cry. Should I just leave it alone??

UPDATE: After seeing her in the hall I said, indirectly but loud enough, “maybe if you have a boyfriend you shouldn’t be on other people’s..” She snapped him that night and he said “bro you gotta back up off me..you know that I have a girlfriend and I don’t like you on me” to which she replied “k”. 😂 She was walking with him today and I made sure to kiss him in front of her. Petty? Yes. #sorrynotsorry

UPDATE UPDATE: Thank you for supporting my pettiness😂❤️ and yes, for those saying we’re in high school we graduate on Saturday! After that day, she doesn’t walk with him or talk to him anymore😌
