This feels very similar to <i>namorar</i> in Brazilian culture, which is a verb that is basically means "become/be an exclusive couple".<p>If you've started going on dates, then at some point someone will ask the other to <i>namorar</i>. It's a very explicit ask, e.g. "let's be boyfriend/girlfriend".<p>While in the US it's not unusual to just organically become a couple and never actually discuss it "officially", the official ask is usually a really meaningful event in a relationship in Brazil. Technically it means that hooking up with someone else before it wasn't cheating, but afterwards it definitely is.<p>But <i>namorar</i> is definitely not "love". And you'd never declare it <i>before</i> going on a first date. Usually it would be after several weeks/months of dating, depending on how serious you felt about each other.
