No Fighting

I've been dating my boyfriend for a year and 8 months now and we've never had a fight. Like, we have little banters... but never full blown arguments or fights. The thing is, we don't have anything to fight about. We have our visits, we have our time apart (too young to live together and I don't plan to until he wants to) and we both are just really chill. Neither of us have anything to get jealous about, nothing.

Here my friends always talk about arguments they have with their boyfriends and stuff then I'm always like "yeah, ____ and I never fight." So I get called not normal for it, or our relationship isn't healthy. But I don't see anything wrong with not fighting....

Thoughts?
