Fans got a behind-the-scenes glimpse at Teen Mom Ryan Edward's breakup with his girlfriend, Dalis Connell, during MTV's one-off special, Being Maci, but what we didn't see? The real reason for their split. Not only did Ryan cheat on Dalis, but she was visiting her dying mother in California at the time!

Dalis visited her mom in early December 2012 (when Being Maci was filmed) after the Dream Foundation learned she couldn't afford to pay for her ticket and offered to cover her expenses. Unfortunately, her relationship with Ryan took a turn for the dramatic around the same time...

"Apparently that show is on & everyone finds out now why Ryan and I broke up!" Dalis tweeted on August 18. "Cheated on me when I went out of town to say bye to my dying mom.. But MTV would fail to show that part."

For those of you wondering, it doesn't look like Ryan cheated on Dalis with Maci Bookout

— though they did party up a storm while Dalis was out of town!

“I actually don’t remember them filming anything else except me talking about leaving to go say bye to my mom one last time,” Dalis tells Starcasm. “And then calling Ryan a million times because I found out he lied about going out and he actually cheated on me while I was out seeing my mom.”

Shockingly, Dalis doesn't harbor any bad feelings towards Ryan, and says "being hateful wouldn't change the situation." As of now, this gal is single, and she hopes to move to California to become a nutritionist/ personal trainer after graduating from college in a year.

“I finally realized I needed to be by myself and start loving myself before I can focus on someone else so as of right now there is no one!" Dalis says. "Just doing me.”

Amen to that! We're sure Dalis will find the man of her dreams in California — but Ryan has some serious explaining to do. Who cheats on their girlfriend while she's out of town visiting a dying parent?! For shame, Ryan.
