Girl came from overseas for a couple of months for a holiday. We went hiking, travelled in a van across states, took her to the doctors, went to zoos aquariums, most places

1. We were a thing but not a thing.
2. Did sexual stuff every week or so
3. She came out of a 4 year relationship and didn’t want a relationship
4. She wanted to go back to her home while she was with me
5. She visited her family in another state 6 now has a job Christmas casual for 2 months
6. Has friends, likes the area 8 now is staying there for 2 years. 9 she kept messaging me constantly wanting to be friends 10 I said I can’t do that, and broke ties, every time she kept trying kept trying I kept ignoring 11 she still has her parts of her stuff here 12 flight back on early February

I cannot analyse the situation and would like & appreciate people’s input

My thought process is hatred as she’s implied she didn’t want to stay now she’s staying happy using Australian slang etc, she didn’t want a relo but pretty sure that meant not with me however I gave her the benefit of the doubt that after her last and how bad it was she wanted a break from it. I got a lack of affection and re assurance & wasn’t able to break it off earlier than I wanted to due to she had no where else to go, I felt bad now feel used not worth anything as I did everything she wanted to make her happy, she even caught a flight to another state for a couple days got food poisening & I had to drive 10 hours to make sure she was okay through flooded waters. couldn’t of done anything more and it makes me feel like if that wasn’t good enough nothing I do would ever be
