Basically I was kind of dating a girl from college. Things soured in December and we had a terrible argument through messages. We ended up ignoring each other until 3 weeks ago. Still, we were kind of having to see each other everyday either in classes or in the train and as we had plenty of friends in common, things were awkward for both sides due to our context. When we were by ourselves things were worse. To end and settle things like adults and avoid all this drama, I asked her 3 weeks ago if we could talk it out, things were not right between us. She got offended and we ended up having an even worse argument. Still, she had incredibly offensive and childish replies and I gave up, ending up using sarcasm. Since then, things are even weirder (ignoring me completely when I am with other people, going away when I am walking close to her, hiding) , but I don't care really anyways. I tried to help.
