<human>: My girlfriend and I recently got back together after a 4 month break up. Before the break up, we had been together for many years. We both hooked up with different people while we were apart, and I have agreed to no longer talk to the people that I had been talking to while we were apart. 

Although she had also agreed to not talk to the people she had hooked up with, she now wants to reconcile differences with one of the guys she slept with. I have always held a grudge against this person, and on occasion we will see him at a party. 

She feels that it's too awkward to avoid him, although I see no issue with this and want her to remain completely out of contact with him. 

I may have not completely let go of what has happened with this guy in the past, but I know that she would absolutely refuse to let me have any interaction with any of the people that I was talking to while we apart, though she is mad that I don't want her to talk to this guy. 

Is she holding me to a standard that she does not want to be held accountable to? And how can I explain this to her if she is without coming off as a jackass?

Can you give me the gist of the text in a nutshell?
