How to make and annoying b*tch JEALOUS of me at School!?!??!?

This girl at my school is really getting on my nerves. I onced liked this guy, who is now her boyfriend. and she knew about it. Well, when i use to talk to her about him, she was cool and i told her how we met and stuff and she would be like"awww" and everything. But, me and that guy got in this big fight about how he never liked me and everything. Like a week later, they started going out. Then she started being mean to me because i guess she still thinks i like him. On facebook she writes stuff to make me jealous...like I really care, IM OVER HIM!!!! Like one time I did this little friend interview and it asked me about the girl. It said "Does______like hugs" And i answered yes, im sure she does. Then she left a comment saying"Yup, hugs from HIM. I was like WTF!?! She thinks she is all pretty and stuff. From my perspective she is okay, but I think im goregous. So, I really want to make her JELOUS OF ME! I want her to look at me and just wish she was me. We both wear A LOT of HOLLISTER, so I think if I wear more Hollister than her she will be jealous and think im richer than her, I just recently bought lots of stuff from Hollister, but not to make her jealous jusst cause I like it. So yea. tell me what I should do. She also gives SLICK COMMENTS in cl. We have one cl together, she says stuff like "Wow, some people just are.....wow" She just says slick stuff for no reason, she is annoying. So what slick comments should I say and what should I do to make her JEALOUS!!!!!!!!!!!!!!!!!!!
