Lena Dunham and Jack Antonoff dragged out split

Lena Dunham and Jack Antonoff reportedly dragged out their split.

The 31-year-old actress confirmed that she and her beau, 33 - who had been dating for five years - had gone their separate ways during an Instagram livestream earlier this week but, although their break up came as a huge shock to fans, the pair had been slowly pulling away from one another for past six months before decided to part.

A source told UsMagazine.com: "They had been slowly breaking up for the last six months. It was very drawn out.

"They took forever to actually break up. It took way too long to pull off the bandaid."

Despite announcing her split, Lena told fans that she was going to continue to wear the ring Jack had given her because it's a sign that the love hasn't just disappeared.

She said: "I'm wearing this ring that Jack gave me, and I'll always wear it because love is a really cool, powerful, eternal thing. It doesn't have to be defined the way that we, in Western culture, define it as beginnings and ends."

The 'Girls' creator then thanked her fans for their "support" during her break-up.

She added: "Things can be, 'You know what, you're a drop of water, and then you re-enter the ocean.' Anyway, I really love you all. I'm really thankful for the support. I'm really thankful for the love."

Despite their lengthy relationship, the pair had never felt rushed to tie the knot, and Lena previously said she was pleased at the lack of pressure the couple had put on their relationship.

She said in February last year: "I am not against marriage in any way, but I do like the fact that Jack and I have placed zero pressure on ourselves about it. I have friends who have met someone, married them and got divorced during the period of time that Jack and I have been dating. We are as close as you can get to a pair of 100-year-old people. Every night we go home, walk our dogs, put them into their crates, take melatonin, watch 20 minutes of TV, then we go to sleep. It is the schedule of ancient, ancient people."
