I touched a girl while making out/kissing.

One summer ago, I met this girl and gone on dates with her (mostly in parks where we would kiss and cuddle).

One time there was a tree and I walked her into it so we could make out. Here's where it gets fuzzy. I remember my hand was under her shirt and on her breast at one point in this and I asked her if it was alright or something along these lines in the moment and she said it was. I am unsure if I asked for her consent before though. This was months ago and I texted her and she said I never made her uncomfortable and she agreed that everything was consensual, but I have a hard time believing this given we stopped seeing each other after that same day I believe, albeit apparently for another reason. We still very occasionally text.

That same day but later on with her while cuddling I asked if she wanted me to touch her down there. She said it's up to you or if you want to (I can't remember) so I put my hand between her legs over her clothes. I stopped though because the situation felt awkward.

Did I do anything wrong? I am unsure if she was uncomfortable in these moments, even though she said she wasn't later on.

I am seriously considering encouraging her to file a report on me. I have also been considering turning myself in.
