"I realized I was gay in fall 2012, one of my first days on the set. It wasn't so much one thing, but the sum of many small details: how uncomfortable I felt around groups of lesbians or how I considered myself (shrug) a 'not very sexual person,'" she wrote. "When considered alone, these seemed like little quirks that made me me. Wanting to read a book instead of have sex is a perfectly reasonable preference to have, right?"

While ending her marriage to "the person I loved most in the world" was difficult, Morelli said that she's grateful to be living the life she leads.

"I went through it all on set: I fell in love with a woman, and I watched my life play out on screen," she wrote. "It feels liberating and appropriate to live my life in front of you."
