Female friend said "I love you" to me even though she knows I like her?

Normally I'd think nothing of it, but she knows I like her and our of nowhere she called me by my first name, and said "I love you." Then the following week she took my phone to get my attention and gave me a random gift, then made fun of me by talking about how I'm still single. Then this week she began touching me randomly, especially on my cheek with her hand, for over 30 seconds. Usually when she's with her friends she always teases me but when we're alone she's a lot more quieter and shy and when she smiles she kind of looks down. Any thoughts on why she said she "loves" me?
