Her rep did not immediately return PEOPLE’s request for comment.

PEOPLE confirmed in January that Dunham and Antonoff, 33, had split after dating for five years.

Dunham revealed in the March issue of Vogue that she underwent a total hysterectomy last year. She discussed the procedure and the outpouring of “overwhelming” and “heartening” support that she’s received from fans in an emotional Instagram post, aligning the experience to her breakup.

“I have a broken heart and I hear those don’t mend overnight,” she wrote. “But we are linked forever by this experience and our refusal to let it hold any of us back from even the grandest dreams.”

In her Vogue piece, Dunham chronicled the hysterectomy process from start to finish, explaining that she made the decision in the hopes of ending her crippling endometriosis-related pain. After “desperately” trying to manage a “new level of pain” from August to November, Dunham said she finally checked herself into the hospital and refused to leave “until they stop this pain or take my uterus.”

Dunham said the situation wasn’t easy on the former couple.

“My beautiful partner, who has seen me through so much pain with compassion and care, has to be away for work, and I can feel us growing slowly apart, since life is so determined to display its full complexity right now,” she wrote in Vogue. “I am surly and distant. I offer nothing.”

“He reminds me again and again that I am still a woman and still alive,” she continued. “But I also know that soon — for so many reasons that have nothing to do with my uterus — we’ll slip away from each other and I will face everything I am losing in impossibly tiny step.”

Dunham and Antonoff met in 2012 after being set up on a blind date by Antonoff’s sister Rachel and comedian Mike Birbiglia.

Days after PEOPLE confirmed Dunham and Antonoff’s split, she briefly addressed the breakup during a livestream on Instagram, saying she was still wearing a ring that Antonoff had given her.

“I’ll always wear it because love is a really cool, powerful, eternal thing,” she said. “It doesn’t have to be defined the way that we, in Western culture, define it as beginnings and ends.”

Antonoff has since been linked to Carlotta Kohl; the Bleachers frontman and model sat courtside at a Knicks game a couple weeks ago.
