I am ox 1985 and my fiance 1985 ox also..we're always fight for a small thing...are we a good couple

Yes, you get a right point on that. Both of you are mighty, self-egoed. It is really hard for you to make compromises. However, you two also share some shinning points, that is both of you are ambitious and industrious. If you get together, you can realize your goal easily. As for fighting, you need to take control of your temper and become more thoughtful.
