Jenelle Evans has called off her engagement to Nathan Griffith for a second time.

The Teen Mom 2 star told Entertainment Tonight that she gave Griffith back his ring two weeks ago, but she doesn't consider herself back on the market. "I'm not looking to date anyone at the moment," Evans told ET. "I am focusing on myself."

Evans, 23, and Griffith, who are parents to 1-year-old son Kaiser, got engaged in January, but their relationship has been a tumultuous one. In 2013, Evans was arrested for allegedly attacking Griffith while pregnant with Kaiser. The couple separated after Griffith was arrested on domestic violence charges in March. In May, Evans was also arrested on domestic violence charges following an altercation with Griffith. A month later, the couple reconciled.
