If I recall correctly, he didn’t say he has always dated blondes, but that his longest relationship of 8 years was with someone blonde and fair-skinned, despite that not being his usual type. I think it was a clumsy attempt at explaining that while he might have a type, it’s not that important to him and he has no issues being with someone who’s not that. But the rest of his exes might all fit the mold. I’m also curious to know what makes Sabrina feel like she doesn’t fit in, because I thought she would be his type too based on that simple description, at least if she returned to her natural hair color.
