Search Results: turned on my just touching

So a few weeks I kind of indirectly told my friend I would never really like her. I didn't want to give her the impression that I didn't like her, I guess it just did. Here's how it happened: I was ignoring my crush and I guess she noticed it, and my crush became really sad around me. I felt bad, so I asked my friend (who's a girl) for advice on fixing this. She wanted to know if I liked my crush, and I said yes. I honestly had no idea she liked me, seeing as she only teased me and she teases everyone. But after she gave me the advice, she began ignoring me for about 3 weeks. Until about last week, but she still acts very different. She begins by lightly poking me in the back and when I turn around she is always giving those puppy eyes, and whenever she speaks it's in a very, very shy tone. But the biggest thing that changed was she completely stopped teasing me. She did it a ton last year and for part of this year up until I told her I liked someone else. Now she just talks quietly, asks how I am, and the weird part is she doesn't say it like her normal self - she says it in a very, very caring/nice tone of voice. She still gets very close to me (like touching me), and she's suddenly just nice to me, and she only acts this way to me, no one else. But she teases everyone else, just not me.

Why is that?
