<human>: To start off, my girlfriend's (We'll call her Amy) prom was last friday (we attend different schools). A girl from my school (We'll refer to her as Tat) that used to go to school with Amy attended the prom as well, and talked to me while Amy was in the bathroom. 

While I know that this isn't exactly the best behavior on Tat's part, Amy's reaction was typical. She got worked up, pissed at both me and Tat for a while after the incident. 

This isn't the first time Amy has been worked up over me having a conversation with another girl- it happens rather frequently. I've gotten to the point where I feel restricted, unable to talk to other girls without having negative consequences later. And so, I've already decided I'll break up with her. 

But that's my predicament. I want to give her the respect of breaking up in person, but sadly our schedules are booked for at least a month. Thus my question: is it acceptable to break up with her over the phone the week after prom? If not, what other options do I have?
