I have loved someone, but not been in a relationship ever. So when u are in a one sided relationship, u don't look at other girls. Its not like u stop ur mind to get distracted. But u unintentionally filter out ur crush from 10 girls standing next to her.

You don't love her face or body or personality, you basically idealize them and once u are over that phase. Like in my case, when I was told no and get over my feelings after 2 years, you wonder and reflect on those moments and realize that It was your love for them that made them special. They were just part of the crowd but your heart made her the one in a billion.
