I hate how people think of face blindness

When I've told people I'm face blind they asked if like, I just see the outline of people's faces, and the few times I've seen it in media it's portrayed as like... you don't see people's faces at all, when I see people's faces just fine, I just don't remember them. Once I was watching an anime with my gf (The Apothecary Diaries, very good anime, just this one detail bothered me) and a character was face blind but he could see this one woman's face cause he loved her so much and it's like........ me remembering people's faces isn't really a matter of how I feel about them it's just like... a disability lol. My gf asked if I can recognize her face and I just said "maybe, but I mostly recognize you by the clothes you wear and your hair" and I feel like she got maybe a little offended, I tried explaining that face blindness doesn't actually work like it does in this anime.
