One time she said she loves me, in a serious tone. Usually she's sarcastic/playful but she looked genuinely serious. Then the next week she made a little pink heart and gave it to me. A few days ago she was with my guy friends (who are her friends too) and she just put her hand on my cheek for over 30 seconds. When we're alone she's pretty quiet and has a more calm tone, but with her friends she's outgoing and loud (even when I'm around) and always teases me about how I'm single and how I should find a girlfriend. She then suggested to get Snapchat but I said no and she looked sad and disappointed.
She already knows I like her, fyi.
So do girls treat guys they like differently? Do you think she likes me?
