A while ago, I came up with a new word that I'd like to share with you:
Affinitophile
Affinitophile (noun): A person who is only capable of falling in love with someone who already loves them deeply, extends unwavering devotion, and regards them with exceptional care. An affinitophile thrives on mutual affection and intense, meaningful bonding and cannot develop any romantic, amorous, or physical attraction for someone who does not already possess a profound love for them.
Etymology: Affinity: Derived from Latin "affinitas," meaning a natural liking, attraction, or inherent connection. -phile: From Greek "philos," meaning loving or having a strong affinity for.
