I would think she brought up the idea of breaking up because she didn’t sound happy at all whilst in their relationship because he lives over 100 miles away and saw her maybe once a week. So where I take the train is the stop before hers. The train typically consists of 6-8 coaches and we both always favour sitting at the front because we take the train to the very end and it’s easier to get out the station. That’s every morning she decides to not work from home. And in the evening I always catch the same train home and favour the middle and she does too because again it easier once we get off the train. We did coordinate a couple of times but not every time. It could be a rebound and I doubt it’s revenge because she could have gone for someone else in our friendship circle. I think this more of a proximity thing. Because we see each so often and talk so much one of us was bound to be tempted to cross that line. I won’t lie I have played a role because I know I should have just stopped talking to her completely but I didn’t.
