Ooof good question!

Had a really great French and Spanish teacher when I was a teenager who inspired me. 

Had a holiday to SW France. 

French girls. 

Realising that learning other languages help you learn your own a little better. 

Then studied it at uni but that it sucked my love for it. 

Then worked at French companies in really small French villages as a young adult. 

And my first grad job was selling ski holidays and hotels for a French company. 

So I guess it’s mostly time in the country + liking the culture and way of life. 

With Portuguese I’m less inspired by the language. Spanish less so. I’ve never stopped to really wonder why.
