<human>: I am a male law student who recently was dumped by a female classmate. We were in the same friend group and did most things together for about a semester and a half. I thought it was great, and she has been everything to me at this school. To be honest, it was the most comfortable, happy relationship I had been in. After breaking up, we hooked up for a few weeks, but she told me that she was seeing another guy a couple weeks back (another classmate). They had originally hooked up the night after our break up, but she admitted it, felt absolutely horrible, and told everyone that she had made a mistake. I know it seems like a lie now, but at the time I felt it was the truth. 

My friends have been great in terms of not picking sides and letting us vent in a healthy way. Unfortunately, she and I sit near each other in nearly every class and neither one of us can move do to assigned seating. We were friends first and our group still does many things together. Furthermore, our class parties and events will always include both of us. We've agreed to try and not exclude each other, but I always end up feeling excluded (but I know that she does too). 

I want to get space and move on, but I feel like I see behind the curtain of her new relationship every day since she's seeing this other classmate. I have other friends in my town and try to hang out with them, but I don't want to miss out on the great things my school offers and making new friends. 

I need some suggestions, Reddit. Does anyone have any suggestions on how to get the separation I need to move on and be happy? Maybe even just some thought patterns on how to deal with the anxiety, sadness, and jealousy I feel when she is around? I don't want to take it out on her, and she knows how I feel. She feels horrible about it, and she says she's being selfish, but I think it's clear we both need to move on. Please help.
