Girl code?

I've been best friends with my girls for 15 years( since elementary school) and recently I've met one of my girls and she called a guy that she likes ( she told me he likes her back). We were hanging and chilling in the suburbs and just chatting with some wine on the side, turn out we have so much in common and would have a laugh about random stuff. They don't have that chemistry when they talk it's just physical. He told me he likes me and then my friend got upset and interrogated him, he told her he was testing I guess ( when I was in the bathroom) but kept on telling me how he likes me and wants to get to know me.. Umm, I like him.. should I respect the girl code and just turn a blind eye?
