The TOWIE couple have been together on and off for seven years, but it emerged last week they'd split yet again, with allegations Arg's partying had got out of hand again.
Speaking on ITV's Lorraine today, Lydia confirmed: "Me and James actually broke up nearly seven weeks ago, which was a tough decision to make but I kind of felt I didn't really have a choice."
The 26-year-old added: "I feel a lot stronger and happier now. I just came back from visiting a friend in Indonesia and went travelling around the islands. It was an amazing trip and I've come back positive and strong and looking forward to the future."
When Lorraine Kelly said that Lydia will always love Arg, the Essex star agreed: "Of course, yes I will." Lorraine then said, "I could shake him sometimes!" to which Lydia replied, "You and me both, Lorraine!"
Neither Lydia nor Arg has revealed the reason behind their split, but Arg has said he wants them to reunite. The star, who is currently at a weight loss boot camp in Norfolk, told Heat: "Me and Lydia are on a bit of a break at the moment. Of course I'm hoping that we'll get back together in the near future."
But he also stressed he need to focus on himself for now. "I feel good," he said. "I've got a long way to go, but I'm on the right path. I do feel proud of myself."
The couple initially met at the Duke of Essex Polo seven years ago, and both appeared in the very first series of The Only Way Is Essex. Lydia eventually let the show in 2012, saying she needed to get away from then-ex Arg in order to move on, but she returned two years later.
Their romance picked up again and although there were issues - we watched as Lydia asked Arg to write a list of women he'd been unfaithful to her with and expressed concern at his drinking – they had seemed happy during the 17th series of the show, even flat hunting together in March.
At the time, Lydia told Arg: "Let's just clear it up, when we say family home, with a family coming in like five years. Because we are doing this, though, getting a house together we need to make it a pact that we can never break up with each other again."
