Fighting in a relationship is important. It shows you if someone fights fair or nasty, if they can remain rational, and if you can actually work to solve issues together. In the honeymoon phase people tend to very agreeable and want to avoid confrontation, so you may have to pick a fight in order to see what happens when the going gets tough. Throwing barbs and purposefully trying to hurt the person you are in a relationship with is not someone you want to be fighting with for decades to come. And yes, you will fight, everyone does. But if both of you are unrealistically agreeable until after you’re engaged or even married and then you find out that they fight mean, well, what then? So go ahead and even let your partner know what’s going on and find a topic you disagree on (politics, sports, the absurdity of reality TV) or something else rather innocuous and see where it leads. Good luck!
