I dont know my bf?

So yesterday I went to the cinema with my boyfriend and his friend 'H'. After the movie we went to McDonald's to have dinner and made small talk.

But then H offered my bf some of his ice cream and then immediately took it back with a "it has walnuts, you hate them". I didnt know that so I asked him and he was like "yh, I dont like any type of nuts".

And then H said "See? I know you much better than her. These are just everyday things." and referenced one of this Facebook 'how much you know me' test my bf had done were I had scored 12/15 and H 14/15.

I dont know if H meant it to be mean but it kind of felt like a low blow. Like he was saying "she doesn't know you enough".

I've been dating my bf for over a year and I know there are obviously things we don't know about each other but that comment hurt. Like now I don't know if there are only small things I know or if I dont know my bf at all.
