Someone pointed out communication problems before:
If you really like someone basic communication while one learns the other's language(or both) is enough, my boyfriend's native language is English and the other languages he is fluent in are French and Spanish, I am German and just had a few years of English classes, he is learning German after having moved here, I am learning English and Spanish. We never had communication problems, sometimes missing a word or forming a sentence wrongly, but if you really want to or need to you can make yourself understood
