<human>: Condense the text into a few key points

I used to date someone who we'll call Courtney, though we were never official. We were more like friends with benefits. This ended about a year ago when I moved to another city.

I came back home for christmas break, and she wanted to hang out again. She said it was a friends-only thing, but sent me a text saying "I can't wait to see you, especially if you're half as cute as you were." The problem is that I'm in a relationship, and have no interest in throwing that away.

At first I agreed without thinking about it, but the morning of the day we were going to hang out, I cut off the plans. Now I think she's trying to guilt trip me with texts saying things like "way to be one more abandonment in my life..." to which I all I said was "I'm sorry." 

I understand this is all over the place, but I'm really not sure what to do. I feel like Courtney and I could still be great friends, but I'm not comfortable seeing her until I know for sure that's what she wants. Should I just cut off contact? I know I was in the wrong for agreeing to see her in the first place, but was I in the right for cutting off plans? I feel like I just lost a good friend.
<bot>: Former fwb wants to hang out with no intimacy involved, I agree then later cut off plans, now I feel like I lost what could have been a good friend.
