I messed up big time

Me and this girl was together for a year (we’re both girls), I broke up because she didn’t have time for me. We remained friends and last night (half a year later) we went out drinking together for the first time. She started talking about how I broke her heart and that she thought I broke up with her because she was too much. I was very clear about why I broke up with her when I broke up but we all have our insecurities ig. So I tried to reassure her that me not loving her was not the problem and that I love her very much. Well this led to her asking «then what’s the reason for us not trying again?” (her situation has changed, she has more free time now) and I just said there was no reason. So she asked if I wanted to try again, she was crying at this point, and I said yes because I thought I could still loved her like I did. We kissed (for the first time, yeah I know, I had some issues when we were together) and I felt nothing, well actually I didn’t like it at all, it was terrible (not saying she’s a bad kisser, I think we’re just not compatible). That’s when I realized that I just love her like a friend. I’m now sober and I feel disgusted with myself and I don’t know what to do.
