<human>: Could you distill the essence of the text into 1-3 sentences?

On New Years Eve, I met a girl. She was great and we got along amicably, and within two weeks we started dating. This was my first ever relationship, and during the relationship I was the happiest I've ever been.

Unfortunately, it wasn't the same for her. At home, her mother was incredibly obsessed with my girlfriend's weight, constantly calling her fat and horrible shit like that (my girlfriend was in great shape as she was a part of a local swim team). This in turn makes her suffer from bulimia, which effected her mental state greatly. I learned about this half-way through our relationship and I tried my absolute best to ensure that she was safe with me and that she had nothing to worry about. She meant the absolute world to me, so I felt I had a duty to protect her.

Unfortunately it was clear that own problems overcame our relationship as we broke up after 5 months. A week prior to it we arranged to go into town for lunch and shopping, but the morning we were meant to go she bailed out. This had happened a couple of times before, and previously I remained stoic, but I lost my cool a bit this time. Later that night I sent a long text to apologise for that, to which she then broke up with me.

3 weeks have passed now and I miss her so much, but I don't feel like at any time I can try and regain communication because I am scared that she might have a panic attack. I still want to help her get her through all this, but she obviously doesn't want/need me, which hurts. Overall, what I want is to have my relationship back with her as I cherished every moment with her, but I have a niggling doubt that it is selfish of me to want that and that it is best to leave her alone.
<bot>: girlfriend suffers from bulimia/anxiety due to abuse at home, breaks up with after 5 months, want her back but scared that pursuing that idea will cause more harm than good.
