Amanda Seyfried and Justin Long have split up after two years of dating, PEOPLE has confirmed.

“The truth is that they actually split up around 2 months ago and never lived together,” a source tells PEOPLE. “They both tried very hard to make it work because they each wanted to eventually have a family but ultimately they weren’t compatible and decided to split up. They are still on good terms and friends.”

Seyfried first got together with Long during the summer of 2013, and she recently admitted to Vogue that it was his sense of humor that won her over.

“I followed him on Instagram and I thought something he said was really funny,” she said. “It was a picture of a snail, and the caption said, ‘F—ing MOOOOOOOOVE.’ It made me laugh out loud so I texted him.”

Earlier this year, Seyfried posted a funny picture on Instagram to wish Long a happy 37th birthday, writing “Happy Birthday Hunk!”

When Does Amanda Seyfried Feel Most Beautiful?

The couple kept their romance low-key – from dog walking to reality-TV binge-watching, Seyfried previously said that she and Long were happy not doing much.

Long dated Drew Barrymore before meeting Seyfried, and Seyfried was previously linked to stars Ryan Phillippe and Dominic Cooper.
