Girls, can you help me better understand her ??? :(?

Okay, I am sorry but this is going to be kinda long and I am tired of feeling like this. There is a girl I like a lot more than a typical crush because in December we almost went out like we were unofficial. We ended up getting into a fight and it fell apart and she went and dated someone else. She would always tell me that she loved me and once she started to date him she stopped which i figured haha. Well fast forward a few months and they are having problems and she calls me and is crying telling me about how they are fighting, so being the friend that i am i go and go to her house and she is crying so hard she cant breathe so i just held her in my arms and got her to calm down. Her boyfriend called at that time and said "awww I made you cry " and he started laughing. This has happened a few times where I have gone over because she is crying. The other day she called me and wanted to hang out because her and her boyfriend got into another fight and she came over to my house, she was sad and we were just watching tv and she curled up next to me and laid her head on my lap and just watched television. She then wanted to go to a movie and i agreed to take her and the entire time she was poking me and saying smile and kept trying to get me to smile and her other friend wasn't there and she didn't do it to her. On the way back home she wanted me to drop her off at her friends apartment which i was against the idea of it. Her boyfriend was gonna be there, they argued and he was supposed to take her home but he left her in the middle of nowhere at night. She called me crying and i drove out there and got her and took her to her house. I thought nothing of it. I got a text from her saying " thanks for everything, and I just wanted to say I love you." I replied with I love you too as a joke but i meant it because i still like her. I thought that was gonna be it, but I got another text message back saying "i love you more :) ". I told her it wasn't possible because I have still had the feelings for her since the fight in December. I never told that i still had the feelings and I came up with the excuse of "im taller and bigger so that means my heart is bigger" and she replied yea yea bullshit. She said her relationship was failing. Could this be her seeing if it would work with us again? She hasn't said she loved me since we fought in December. Can you all give me some help?
