Will we work? Relationship help!!

So there is this guy I've been talking to for a month and been on 3 dates with! We have great chemistry! But I just got over the honeymoon phase and I'm starting to realize that we are polar opposites( both the big stuff like sex and marriage and the little stuff like music)! One of my friends thinks that I should end it because I can't see us long term while the other thinks that this is just a rough patch that I need to get over and fight for the relationship! Help please!!
