Upset with a "friend"

When you tell your friend you like a guy and she lays her legs all over his lap and gets his Snapchat and messages him all night..after she said she didn't like him and is not attracted to Latinos. I'm just keeping everything to myself now. She's the type of girl who always needs to be in a relationship and has a very flirtatious personality. Which is fine, but don't target the guy I told you I like and that I was scared to talk to. It's so messed up. I guess I am moving on him from now because he is being flirty with her as well. 😟
