I met him through her and we've been dating for a while now, he has known her since they were kids and they're really close, she calls him alot. She flirts with him right in front of me too. She touches him a lot whenever im around. And she gets all weird whenever he touches me at all. i know he doesnt like her. Even though i know she doesnt like him more then friends, so why is she doing this? Why is he letting her? What should i do about it? Should i say anything?
