Girlfriend still friends with guy she cheated on me with?

A-Vengeance
Earlier this year I suspected my girlfriend was cheating. From what she told me bout the guy, how she acted, and what she did, I told her she was cheating but she kept denying. One day out of the blue she breaks up with me over a text then acts like the victim. Last month we talked about what happened. I threw all the evidence I had of her cheating an lying in her face until she had no choice but to admit she did. She admitted she cheated on me but insisted she didn't know why she did, she kept asking if I knew what she was doin why didn't I say anything? I did this whole year until we broke up. She started to act like she was the victim sayin I wanna get 2 kno each other again too but you don't trust me.3wks later we got back together. I told her I don't trust her with him an she said shell stop hangin round him but I told her she could cause she was friends with him b4 she met me so I didn't want her to lose her friend.(Stupid on my part) Its been 2wks since we got back together an she still talks to him and gives him hugs wen I'm not around an gets all laughy an goofy too. The other day she tried to lie to me sayin she was walkin home but halfway down the street the same guy was walkin down the street an yelled "so ill just meet you @ the skool". During skool I heard one of my friends say to her that he was lookin 4 her that mornin cause they had plans or sumthin. An after that they were talking after class @ her locker. Then that happened. Now I hear from my close guy friend that wen she comes back to class he's the 1st one to come look 4 her and hug her. An jus b4 class she goes in his class to mess around with him. To me its more of the same crap that we went through b4 we broke up an I'm not dealing with it again. Ill admit she's more into me than him wen compared but the fact that she says she's uncomfortable kissin me says a lot about what's going with him an us. Is it a good idea to tell her that "I don't care anymore that he's your friend but I can't deal with this again, either you stop flirting with him or I'm gone for good. you don't see me huggin or being all flirty with any girl in front of you or behind your back so I deserve the same"? I kno its a good idea but I don't wanna sound like a jerk cause since we got back together I havnt been takin any of her crap an I've been on her case about her lying to me an still doin the same about everythin but this an now I'm gonna say sumthin bout it too. A more better question would be What would be a good way to phrase it?

I'm not upset or anything. I stopped getting sad over her a while ago. Now I jus get mad cause she should kno better.

It was her choice to get back together. She knew I still had feelings for her.
