I also saw his mother and she has an even longer nose (not naturally), and I also just had a burned-out light bulb turned on, is this a sign of the gods that this man is Jewish?
When it comes to the hooked nose, it is featured on some people of Mediterranean (North Africans) stock and I noticed on in some Turks that come as tourists in my city.
Some other races can have large noses, too, you might need more proof. Big Dumbo the Elephant ears are common on yehuborim, as are giant foreheads, soulless beady eyes, and having a New York City accent, no matter where they are from.
Those are definitely characteristics that can be noticed on them when it comes to appearance, and if could think of one famous person who fits the description you just gave Kouros, it is (((Danny Devito))). As AFODO mentioned, you have not seriously engaged in this relationship, so you can backpaddle out of it and seek out someone else.
Also, my second sentence where I mentioned avoiding the relationship is aimed at the OP who asked the question and not Kouros. Just noticed that the ambiguity due to an earlier sentence might cause confusion.
