It's normal dear, no worry, as long as that is not hurting each other alot.The couple that fights the most is the one most in love... it shows they care enough to notice the other one screwed up and care enough to mention it to the person so they can fix it. When you stop fighting it means you stopped caring.

Don't let someone become your everything, because when they're gone you have nothing! Love is never wanting to lose faith, never wanting to give up, and never truly moving on. Love is knowing and praying in the deepest part of what's left of your heart that they feel the same. If we are to judge of love by its consequences, it more nearly resembles hatred than friendship.
