Did I do the right thing?

I had a one night stand ages ago, and she initiated it, tho yes it takes two I know that.

Anyway that’s all it was, about 8 months later we start talking again and she brings up what happened saying she’d liek it to happen again, I tell her I don’t want anything serious straight away so as not to cause confusion, which she is fine with.

So we come up with an arrangement to have some good no strings fun when we could, and this went on for about 2 months with no hic ups until she wanted more, now at this time I live 4hrs away so said it wasnt viable and she agreed, saying if I lived closed would I give it ago, and I said yes.

Well I turns out I had to move back home for a few months due to money reasons and well she lives close, so true to my word I “had ago” we saw each other more hung out and made it not just about sex, but still in my eyes thats the only thing we clicked with, the conversation was not much, our interests were miles apart and we just didnt get on, she being blinded by feelings took it bad when I said I wanted 2 end it - we had only been dating for 2-3 weeks.

I wanted to do the right thing and not use her because I do like her but no enough, and so as not to take advantage for a couple of months and then leave her when I moved away again I ended it early. Hoping she’d understand that I always said what I was going to do I never lied, I only offered what I had to give and never made any promises. I feel really bad tho still, and I think she understands on some leave but it will take her some time to see I’ve done the right thing

I guess I just want some confirmation.
