"Your heart just breaks, that's all," wrote the 2012 Miss USA champion and subject of Jonas' hit song "Jealous." "Heartbreak is hard but you find more and more things to be grateful for every day."
Alongside a photo of palm trees in front of a sunset, Culpo also gave a shout out to her fans: "One of those things is all of you. Thank you all. Yes I'm going to be okay and I love u guys so so much."
Culpo and Jonas started dating in August of 2013. They were last seen together at the Billboard Music Awards in May, though Jonas confirmed to ABC that the two were together as recently as last week.
It sounds like a tough split, but at least Culpo is looking to the bright side.
