In December of 2019, she wrote: "I fought with Babi again. This time it was serious.
"I hit him, I cursed at him and he broke down the door.
"All I wanted was for him to ask how I am when I woke up. I woke up so weak and tired.
"I am thinking of leaving. I am thinking of going to my sister, I don't know if I can keep going with Babi.
"I love him so much that I can't leave him even though this relationship hurts me."
Caroline writes in another entry in 2019: "Last night we fought with Babi because I had a meltdown because of my hormones.
"I yelled at him and hit him and told him I don't want our baby...
"I am not well, I am very upset, I know he would never hurt my baby.
"My love for her is stronger than anything in the world.
On July 3, 2020, when her baby daughter Lydia was a month old Caroline wrote:"Today my little one is a month old- it's also the day I told Babi I want to leave...I feel awful."
She continues by saying she found a house in Halandri, a suburb of Athens and adding that she was thinking of leaving him before she got pregnant but eventually "stayed with him because I didn't want my daughter to grow up without her parents."
The diary includes several entries where Caroline blames her hormones for the couple's arguments and says she feels "embarrassed" her hormones affect her so strongly.
Caroline had allegedly messaged a pal on the night of her death, telling them she was leaving Babis.
The 33-year-old confessed he strangled his 20-year-old wife when she vowed to leave him and staged the crime scene.
He initially told police that a gang of Albanian criminals had broken into the couple's home in Glyka Nera on May 11.
Police have described him as a "top-class actor" as he was pretending to be devastated by his wife's death for 38 days.
According to the investigators he even drowned the family dog and hung its body from a stair banister to blame it on the burglars and strengthen his story.
Cops travelled to the island of Alonnisos where a memorial service for Caroline took place and asked him to follow them in order to give new testimony about the murder probe.
Babis reportedly begged them to allow him to visit her grave before being taken to Athens.
After an interrogation of eight hours, he admitted he staged the burglary to "keep custody of their baby daughter."
Greek police was able to see through his lies after examining the couple's smart devices.
An app on the pilot's phone designed to count his steps revealed repeated movement from the attic to the basement of the home at the time he claimed to be tied and blindfolded.
Additionally Caroline's biometric watch showed heart had stopped beating hours before the time Babis claimed she must have been murdered.
It has emerged that the brave Brit fought her husband for ten minutes before her pulse stopped.
His timeline of events was further discredited when police discovered the memory card in the security camera of the maisonette the couple shared had been removed at 1:20am.
Babis appeared in court today and was charged with intentional homicide and animal abuse as well as with false accusations, according to .
He requested an extension of the deadline which was accepted and he is expected to present his defence on Tuesday.
Meanwhile, he remains in custody at Hellenic Police Attica Headquarters.
