Is a language barrier a deal breaker?

Anonymous
I really like this guy i met in Germany when i went there to visit and he knows some English but he i would say his English speaking is average so we have pretty "basic" conversations so that he can understand me, i have tried learning German but i suck at learning new languages i only know the basics of German which i got taught at school but not enough to have a proper conversation in German, What i would like to know is would this be a deal breaker? Having a language barrier that is..
