Aromantic

Aromantic (often shortened to aro) is a label used by people who lack the ability to feel romantic attraction.

Modern History
This term was originally coined in an AVEN thread titled 'Relationship Definitions' in June 2005. While this is not the first use of the split attraction model it is one of the first mentions of the term aromantic. After this there is very little mention of aromanticism until 2010, when aromanticism begin to gain a community on AVEN.
