Yes, if you are asking me, one cannot expect to live in any country and not communicate with its inhabitants. The notion that some Expats have that Ecu adorians should speak English is an embarrassment to all of us. So, you will need to learn Spanish. It will not be your first language and the learning process comes with some amusements along the way.
Yes, it is a challenge but learn, you must!
As my wife is a certified teacher, she says that not all folks learn in the same ways. We’ve done on-line courses, computer discs/programs and once here, even connected with a tutor. I’m honestly not certain that any of that helped me very much. I think we’ve both learned more through our immersion in the culture…just listening and asking for help from all we meet. After about 15 months, I am, in no way, fluent!!! I can barely get by. I’m guessing after maybe 3 years…or 4….I will be much better than I am today and today I’m much better than the day we arrived.
