<human>: Give me a shortened version of the text

Obligatory, sorry for bad english, I am from Germany and english is only my second language. 

So theres this girl,let's call her Lily, that I've known for a few months now. We became friends pretty fast (we are in the same class in school). 
She then got together with someone in our friend circle, lets call him Eric. She broke up with Eric after 2 months which happened like 3 weeks or so ago. 

She is in general a girl that is very happy and not afraid of physical contact so I didn't think much of little things she did before like sitting really close to me, laying her head on my shoulder or linking arms with me.
 

2 days ago we all went to the beach and got drunk and she became even more physically close then before. Lots of hugging. She also held my hand a lot that night. Like when we lay next to each other in the sand looking up into the sky she grabbed my hand, held it tight and stroked my fingers and inside of the hand which I did too in reaction. And on the bus ride back, she took my hand again and laid her head on my shoulder almost falling asleep and every now and then took my hand or individual fingers and kissed them. Again I put this off as her normal personality just being increased by a lot because she was so drunk. 

But yesterday I went for a walk in the evening around the neighborhood with her. What initially was planned to be just a quick walk ended up being 3 hours of us discovering new parts of town, climbing over fences to get into private playgrounds, talking a lot and just enjoying the moment. After the first 30 minutes of us just walking next to each other other she linked her arm with mine and then slowly put her hands into the pocket of my jacket where I had my hand and then she grabbed my hand there and so we held hands for most of the walk, sometimes changing hands. And after we went on the playground she wanted to hold my hands again. 

Am interpreting too much into it? Holding hands doesn't seem like a thing she would do if we were on a purely friendship basis. Should I make a move?
<bot>: Girl already showed potential signals before, held my hand during a 3 hour walk, I am confused if this is meant to show me romantic interest or if I am so deep in the friendzone she is comfortable holding hands with me.
