Advice on understanding women- Please give me your thoughts.?

Hi! I am having some difficult time understanding the intentions of a particular girl. Being a guy, I realize that there are many differences in the way men and women think, for example, guys seem to have a problem understanding when a girl actually means 'no', because many of us guys will find that a woman's 'no' actually means 'figure it out'. In the same way, women seem to have difficulty understanding how men prefer to show their emotions through actions rather than speech. Anyhow, I have this wonderful female friend who is two years younger than me. She had a boyfriend and I had a girlfriend but we go out on 'friend-dates' (just the two of us) once or twice a month- and whenever we are alone together, she always complains about how unmanly her boyfriend is. One terrible time, I attacked a pitbull because it tried to be aggressive towards her and I just pinned it down on the ground. She said, "Wow, my boyfriend would have ran away." <-- The worst part is, her boyfriend was in the other room and we had no idea, and yes he heard everything she said. She sometimes calls me out of the blue and asks me if I had breakfast, and if I say no- which is most of the time because she calls me so damn early in the morning, she would either bring me breakfast or invite me over to enjoy her delicious home-cooked meals. Now, when we first met, she seemed rather flirty, but then it kind of changed when she asked me my women preferences which was 'I tend to like older women because they know how to treat men.' Since then, she still brings me breakfast and we still do the same things as always, but she has been saying, 'I really like you as a brother.' She always invites me to her house on special occasions such as Thanksgiving and Christmas- and they are always absent of her boyfriend, and I have a wonderful time with her family. I rarely contact her first, and she just recently broke up with her boyfriend, and as hilarious as the timing is, I ended my relationship with my girlfriend. Currently, I am on vacation in Europe but I have been talking with her via international calls. Every time I am about to end the call, she always yells excitedly, 'Make sure you call me again soon!!' Yesterday, when I finished talking with her, she asked me to call her again soon. Then a few minutes after, she sends me an email telling me how much fun she had talking with me and that "I am always such a good friend"- along with some more pep talk. I think I'm falling for her. Perhaps it's because I just got out of a 2 year relationship, but at the same time, I was always attracted to her because of her caring/motherly nature. Not to mention, she is quite beautiful, but I feel it is more important that I know for a fact that she is trustworthy. Anyhow, I have expressed the details with as little bias as humanely possible. I have found there is a natural human nature to conceal our true motives by confusing the other, especially when it comes to relationships between the opposite sex. So based on what you know, do you think she may have similar emotions as I am starting to feel for her? Or does she clearly just want me as a friend and I am over-looking the blatantly obvious? Please let me know~!
