Major bf and friend probs?

so my friend Carin went out with this guy named austin for 2 days and then they broke up since they didnt kno eachother enough and that was a few weeks ago and now Carin and my other friend June like austin too and each of my friends think that he likes them but we dont kno which one is true, we dont want our friends to get in a fight, wat do u think they should do. and carin and june talked and carin told june that it was ok if she went out with him and carin was cryin so we could tell that she really didnt want it to happen. And when june wasnt there she said that it would tear her to pieces if june went out with him. do u think the girl code applys to this 2 day relationship
