Is it normal for me and my cousin (female) to sleep together and hold hands?

A few weeks ago my cousin came over and she ended up spending the night. we have always been very close and we have always told each other things we would never tell anyone else. so that night we were laying by each other just talking and laughing and she ended up laying her head on my chest talking. and it went on for about 15 min then she layed by me on my shoulder and gave me a high five and we ended up holding hands talking while laying there and that lasted for about a hour then we were getting ready to go to sleep and we were still holding hands and we were still talking and every time we would say a word we would squeeze each others hand she turned over on her side and pulled my hand twords her and she put her other hands on ours that were already locked together. and then we locked are legs together at the same time. and we ended up falling asleep like that. now I wonder does she like me in a different way then just family. by the way there's like a 2-3 years age difference in between us. (I'm older)
