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

I (24/M) was with a girl for 6 months. We met traveling earlier this year. She wanted to pursue me when we got home. I agreed. She came to visit, then broke up with me cause she didn't even think I liked her. She then came back to my town we got back together then a week later she ended it again. We got back together 5 days later, then 1 1/2 months it ended again cause she didn't see a future with me.
10 days later she is contacting me again saying she misses me.

 We were supposed to meet up but then she never got back to me. In that 2 weeks I decided I may have to go back to Australia to finish my degree (Im a dual citizen) I called her out on it and turns out she has depression and has had it severely before. I left for Australia because I thought it was the right thing to do and get my degree. Before I left I saw her in person and she already seemed over me. After being in Aus for 2 weeks I messaged her saying its tough down here being back at school and Im always thinking about her. She said the same back, but then the next day she sent a giant message saying good luck with everything, Im not wanting to get back together, you're special to me Etc... I haven't responded nor do I think I will ever message her again.

Im really heartbroken right now but breaking up 3 times in 6 months is not normal. And she has depression and Im almost certain she is already sleeping with other people. Obviously after a break up you can have wishful thoughts but I don't know this time.

What do you people think? I know people can look in the past and come back to ex lovers but I don't want wishful thoughts. I think this relationship is completely done.... Its really the thought of her with others even though she said she's not dating anyone and doesn't want to.
<bot>: Met traveling, broke up 3 times in 6 months, she has depression, I moved down to Aus, contacted her, she says she's not wanting to get back together. Delete or just ignore?
