12 TV Breakups that Left Us All Traumatized (4 of 7)

6. Lily and Marshall, How I Met Your Mother

When it came to relationships, Lily and Marshall appeared to be models of stability. So when they break up in the first season’s finale, it was a huge surprise. Much like Marshall, the audience had to spend the summer coming to terms with this new reality.

7. Willow and Tara, Buffy the Vampire Slayer

When it comes to TV breakups, Alysson Hannigan seems to be a pro. Long before she starred as Lily on “How I Met Your Mother,” she appeared as Tara on “Buffy,” ending her relationship with Willow after disapproving of the way she abuses her magical abilities. What made this even worse is that Tara dies shortly after they rekindle their relationship.
