You'll find over time that your friend's focus on responsibility, stability and dedication draws out your own rebellious, independent side -- the part of you that refuses to be pinned down and will do anything necessary to ensure that that doesn't happen. Knee-jerk reactions could become all too common if you aren't careful in your behavior. This comes down to a basic difference in values and in your needs within the friendship.
Keep your lines of communication open and clear, and talk it out. You'll be able to reach a compromise if you work at understanding each other's motivations.
