Amy Nuttall has reportedly asked for a divorce from her actor husband Andrew Buchan after he left her for a co-star.
Last month, it was said the 40-year-old - who married Andrew in 2012 - was 'crushed' and 'crying almost every day' from the sudden split.
The couple share two children together.
It was said that he moved on with his Better co-star Leila Farzad, 40 - leaving Downton Abbey star Amy heartbroken.
It is understood he told Amy he was leaving her just days before Christmas.
However, it seems that Andrew and his new lover have now 'split'.
Sources have claimed that Amy wants to "take back control" and divorced her husband.
"The shock twist is that it sounds as though after all the hurt and heartache, Andrew and Leila have actually split," the insider said.
“However, that hasn’t done much to change Amy’s mind."
The source continued to The Sun: "She’s told him she wants a divorce anyway. She’s been publicly humiliated and the pain has been unbearable."
Mirror have contacted their representatives for comment.
Last month, Amy allegedly said she couldn't talk about the split rumours, stating: "I can't say anything".
A source said Amy had been left devastated as she tries to rebuild her life.
They said: "It's been very hard for Amy. She's been crying virtually every day since it happened and she's struggling to cope with things. She can't even bring herself to talk about it as she's still trying to make sense of it all.
While a friend added: "Amy and the kids have been hit very hard by this, as you can imagine. They are all crushed. One minute they were living an idyllic family life in a beautiful house and the next, Andrew walks out on them," reports MailOnline.
Leila, who Andrew reportedly left Amy for, was portraying DI Lou Slack on Better while Andrew played Col McHugh.
Andrew, who plays the head of the Leeds criminal underworld, is from Stockport, Cheshire and is best known for starring alongside Michelle Williams in All the Money in the World and ITV's Broadchurch.
Better launched on February 13, with all five episodes going live on BBC iPlayer on the same day.
