I agree that this song is about a relationship. However my interpretation for the part regarding the word "fight" here in context is different. I am going to use first person perspective to explain it clearer.
The fight here does not mean fighting against each other...it's fight to keep each other together despite the differences.
Note it says: Fight, LIKE US to "meet in the middle" which is opposed to Fight, LIKE THEM...as can be seen in the next line that follows "We don't wanna be like them" ("like them" meaning the rest of the average couple).
Because if we fight FOR each other...only then "we can make it 'til the end" and nothing will come between us.
