However, we can say that they dated at least 6 times, with significant breaks in between:
* Season 1: Their first, very brief, relationship.
* Season 2: They rekindle their romance for a few episodes.
* Season 3: They have a short, tumultuous relationship.
* Season 5: They briefly reunite after a long break.
* Season 6: A short-lived relationship.
* Season 8: They have a brief fling.
It's important to note that they were always on the verge of getting back together and often had casual encounters during their "off" periods. So, while the exact number of times they "officially" dated is difficult to pinpoint, it's safe to say they were a significant presence in each other's lives for a long time.
