<human>: So story is my gf 23 and I (m) 23 dated in high school since year 9 for 7 years then broke up for 2 year and now dating again for 1 year nearly. Before we got back together I liked a different girl who screwed me over and got with my now gfs bf at the time. My current gf still hates her so much for that and I did to but it's been over a year and I'm over it, I haven't forgiven her but I'm not letting something like that bother me. Problem is the girl my current gf hates is in the same group as my uni friends and when ever I want to see my uni friends the girl we hate is there. See the problem? My current gf thinks I'm being all friendly with the bad girl and stuff when I'm not, I try to not talk to the bad one and but I can't give up 5 of Mt friends because one my current gf hates.  The bad girl isn't on my Facebook nor do I have her number, the only time I see her is when I want to see my uni friends. My gf just stormed out of my house because we got talking about it nd I said I can't give up my group of uni friends because you hate one, I told her she's not on my Facebook or anything. 

What can I do? I want to show my gf that I'm not friends with this other girl and that I don't forgive her for what she did.

Can you provide a brief rundown of the text in within 3 sentences?
