Input: Bit of a long story, we never officially dated because when we met we were studying abroad together and she had a boyfriend back in her home country. By the end of our time abroad we'd pretty much been a couple for several months in terms of how things were when we were alone together. When we were around friends though it changed and everything had to be kept a secret, which took a significant toll on my mental health. 

After our time abroad she broke up with her boyfriend and went back to her home country in Europe and I went back to Australia. She didn't want a label but she wanted me to come visit her around my exam time and when I told her I couldn't she got nasty saying that I would never achieve any of my goals because I couldn't follow through with little things like travelling to see her. This was one criticism amongst many that she had including criticising my choice of engineering discipline because it showed disregard for the environment, as well as for the political affiliations of my friends, not being vegetarian and a few other things.

The constant criticism hurt me, I felt very depressed at this point, a lot due to me not re-adjusting to life at home after my year abroad, but the relationship didn't help either. Before she met me there was another guy she had feelings for who left because of her boyfriend. Hearing that she was then single, he came back into her life and they started travelling together and I felt very uncomfortable with it, and despite the fact she promised that it was me she wanted, I didn't feel I could trust her. This was the point where I had enough and I stopped responding to a lot of her messages. She ramped up the scale of the abusive messages she'd send and at times she'd hit a nerve and I'd respond. 

For about 6 months this carried on until she called me out for being an asshole who didn't ever care for her and was too immature to hold down a relationship. I did know that she was also struggling with depression as much as I was, but I felt so much better not talking to her so I just couldn't bring myself to respond, or really communicate that to her. I know I should've tried explaining that to her but I found it too difficult at the time. 

When I finally got around to explaining that I left because she was hurting me, and apologised for not communicating or ending it in the healthiest way, she told me that I was just trying to make myself out to be a good person when I'm not by apologising and didn't believe I was genuinely sorry. She believes that me handling breaking it off by not responding to messages was much more harmful than anything she ever did to me and that I'm the asshole here. I find it hard to objectively view this situation, please help me Reddit.
