Not sure if she loves me or we are good friends?

One of my childhood best girl friend(lets call her X) I met today at one of my classmate(she is a girl too and lets call her Y) and we chatted a few times but not so often.
One day the three of us went out to a pizza and there we laugh and she had a lot of fun after that we went on a walk to a store while it was freezing cold outside and she wanted me to hold her hand (like a couple for over 30 minutes). When we arrived at my classmates house we watched a movie after that my classmate had to meet his bf for a few minutes and we had to chat with each other so I started the conversation and after a few minutes she started playing with my hair for 5 minutes (but she got embarrassed when she saw my other friend coming back to the room) and now she keeps messaging me on skype first and once I tried to be a good guy and not bother her (we were chatting for 4 + hours) and she said she is happy to talk with me . (I have a crush on her and I always do start the conversation but after this day it seems the opposite )

She showed me lots of creepy and cute secrets about her and I told her that I accept her the way she is.
Now that the three of us got reuinited (we were really good friends in 1-5th grade) they want to go on a vacation after 12th grade. My friend told us that we can go to the black sea(my crush X asked with who and Y told her that "she , her boyfriend , X and me" and I told them I don't know about this then she responded quickly "If he doesn't go I won't go either").

But sometimes she says things when we are with others that "I am so proud that we are good friends again" and stuff like that .

Now I really don't know what she wants ?

PS:We are all 16 and I ignored her for over 4 years
