"Teen Mom 2" star Jenelle Evans has called off her engagement to Nathan Griffith once again.

It's been two weeks since the 23-year-old MTV reality star called things off, but she's just opening up about it for the first time now, according to Entertainment Tonight. The two had gotten in an argument when Evans failed to find a babysitter for their child Kaiser, and Griffith got mad because he couldn't go out. She's already given him back the ring.

"I'm enjoying being a mom," the mother of two said. "I just celebrated my first son's 6th birthday this weekend and it went fantastic. I am not looking to date anyone at the moment. I am focusing on myself."

The couple got engaged earlier this year in January and have one child together. Evans also has a six-year-old son Jace from her previous relationship with Andrew Lewis. Griffith has a daughter named Emery from one of his previous relationships as well.

Griffith was noticeably absent from Jace's zombie themed birthday party, but he was there to support her when she celebrated her recent graduation from miller-Motte Technical College a week ago, according to MTV News. Here, she earned a medical assistant degree and tweeted a picture of what seemed like a happy family. "Thanks to my family for being here as my biggest support system and able to push me through it!!!" she captioned the photo.

This isn't the first time in the past seven months that the two have broken up, according to Us Weekly. Back in March, they split when Griffith was arrested for domestic violence against her. The two eventually worked things out and got back together a few months later in June. With such an on-again, off-again relationship, it's hard to tell if this breakup will last, but Evans is staying strong through it all.

"I'm so glad I'm as strong as I am," she tweeted on Monday. "Despite everything I can wipe away my tears and focus on me."
