To say that 2014 has been a tumultuous year for the on-again, off-again romance of Justin Bieber and Selena Gomez would a classic understatement. The year has been an incredibly wild, emotional ride for the two stars, from start to finish.

Ashley Rose at Cambio was fascinated by the rollercoaster romance of the star-crossed duo, so she compiled a list of the most epic moments in the 2014 version of their relationship. Here are those stand-out Bieber-Gomez moments that went down this year:

1. The year kicked off with those random, Segway rides...

2. At the end of January, Gomez reportedly checked into rehab.

3. On March 7, Bieber and Gomez were spotted enjoying treats together in Texas.

4. On March 10, they posted that dirty dancing video online confirming they were together...then took it down.

5. These two were always sneaky. Like on April 9, when they weren't photographed together but were totally at the same studio. His protege Madison Beer let that one out of the bag when her mother posted a picture of Gomez with her daughter at the studio...shortly after Bieber posted one with Madison at the same studio, too.

6. This is when it all went bad. Sometime between April 22 and May 28, Gomez not only cleaned house on Instagram, but Bieber also posted a sexy pic with Kylie Jenner starting all kinds of drama.

7. On June 17, they were seen at their mutual pal's birthday party. It was the first time they were seen out together in two months.

8. Just days later, the two stars were spotted at the Los Angeles Zoo attempting to have a normal date.

9. Three weeks later, things went south again. Beiber posted random, sexy selfies with Yovanna Ventua.

10. Gomez was all about revenge on her birthday in July. Remember those jet ski pics with that hot guy?

11. At the end of August, Bieber did his usual thing...and posted a selfie with Gomez confirming they were back on...again.

12. A few days later, they jetted off to Canada...and that ended with Bieber getting arrested for dangerous driving and assault.

13. In September, they went to Las Vegas where they were spotted poolside, and celebrating a pal's birthday together.

14. Days later Justin posted a video showing off his cooking skills...and Gomez.

15. In October, Bieber was photographed with the Jenner sisters at Paris Fashion Week. Gomez was there too, but reportedly jetted home early because he went out with Kendall while in the city.

16. Next comes Gomez's video for "The Heart Wants What It Wants"- visually showcasing how much of a jerk Bieber has been throughout their relationship.

17. On Nov. 13, Bieber unfollowed Gomez on Instagram...and if history repeats itself...then we all know what that means.

18. In the beginning of December, Gomez declared in an interview that she's single.

Now, are you ready for what's in store for the duo in 2015? Hang on.
