there is this girl i my class that i really like and i think she really likes me too. we are always talking and laughing together and i notice her staring at me a lot and when i say hi to her she smiles and blushes and says hi back. also she is really nice to me and tries to make me laugh a lot. she also finds excuses to touch me and she always gives me the "puppy dog eyes" look. but today i tried a little experiment to see how much she likes me. usually when i walk into class and i see her i smile and say hi and she smiles back and we start talking and good stuff but today i decided not to say hi to her or start talking to her and see what she did. she didnt say a word to me all class. so now i am wondering if she still likes me? yesterday me and her were working together and she was smiling and laughing and touching me a lot. but now i am unsure if she really does like me. what should i do and should i ask her out?
