paragraph_text: Barney Stinson is one of five main characters on How I Met Your Mother.

Throughout the earlier seasons, Barney is a huge womanizer, and has been described as a`` high - functioning sociopath'' by his best friend, Ted Mosby (Josh Radnor). Barney has a plethora of strategies and rules designed to meet women, sleep with them, and discard them. Through several seasons of the show, four (4) of the main characters are couples, as Ted began dating Robin Scherbatsky (Cobie Smulders) and Ted's roommate Marshall Eriksen (Jason Segel) becomes engaged and later married to Lily Aldrin (Alyson Hannigan). This leaves Barney the only single character, and, according to Harris, Barney is ``resentful ''that the other characters have paired up. Later on, in season 5, he dates Robin.
