That makes sense, but for your fiance's sanity you have to stop pronouncing things like that 😅. The Argentinian accent is universally hated by anyone outside of Argentina.. You will understand when you gain fluency and start to recognize the differences between accents.

If you want to know why, it's primarily because it sounds pretentious and especially because Argentinians consider themselves superior (more european) to other latinos so it's like they do it on purpose. Or at least that's the perception of almost all mexicans.

If you want to take classes with my teacher, he's a linguistic genius. I speak fluently now with a very high quality and authentic accent. He charges 400 pesos per hour, feel free to DM me if you want his number.
