Language Barrier

I live in south Florida. So it’s literally a melting pot of every ethnicity nationality religion race gender you can think of. Which is a part of the reason I never want to leave. I’ve gotten used to deciphering Spanish, jamaican, and Israeli language without speaking a drop of the native tongues. But I’m talking to this Italian guy and I want to get to know him better but half of the time on FaceTime I have no idea what he’s saying. I just nod and laugh even when he keeps repeating something. I’d say 70% of his English is perfect but God that 30% I’m just like WHAT ARE YOU SAYING?! Has anyone dated someone with a really heavy accent do you have any tips and I cannot learn another language I can’t face the Duolingo owl so please do not suggest that
