Lena Dunham opened up in a big way about her thoughts on marriage and choosing social media to tell her boyfriend Jack Antonoff to propose already.

When SCOTUS concluded that same-sex marriage was legal on June 26, Dunham immediately took to Twitter to celebrate the good news and also remind Antonoff about proposing. Antonoff didn't react at once and instead took 11 hours before replying to the tweet as reported by E! Online.

In an essay she wrote for The New Yorker titled "The Bride in Her Head," Dunham detailed how she regretted posting the tweet.

"I tweeted, '@jackantonoff get on it, yo,' followed by my immediate and all-consuming regret," she explained.

Dunham added that it took her a while after the tweet to realize that she and Antonoff had different thoughts about marriage at the time.

"Jack didn't text back, which is entirely unlike him, and it wasn't until I got home and looked him in the eye that I realized just how little the concept of marriage had been on his mind," she wrote.

"I suppose, it's because, as a man, his entire life has not been shaped by a desire for, or a rejection of, a fluffy white dress," she further said.

The subject grew heavier as they had to attend a wedding after the SCOTUS ruling.

"I held Jack's hand and said, 'Let's not talk about marriage for a while, O.K.?'" the "Girls" creator said in the essay. "He looked grateful and relieved. I felt unburdened but sad. The subject wasn't particularly loaded for him. It never would be."

Afterwards, Dunham gained more realizations about marriage.

"The fact is that wanting everyone to have the right to marry and wanting to be married are two very different things," she pointed out.

"Wanting eternal love and wanting a sit-down dinner with all of your family and frenemies are different things, too," she also said.

It was only last March that Lena Dunham spoke of her understanding with Jack Antonoff to Ellen DeGeneres as reported by People. She said they agreed not to marry until the right to marry has been bestowed to all regardless of their sexual preference.

"It somehow became understood, between us, that we wouldn't even consider marrying until every American had the same right," Dunham explained on her essay on The New Yorker.

Lena Dunham took to Twitter again to share the essay tweeting "some thoughts on marriage," which Jack Antonoff retweeted with the line "very beautiful."
