The fashion designer ended up in tears after confronting Arg at Mike Hassini's secret agent-themed birthday party on Sunday evening's episode, telling him he had hurt her time and time again.
Viewers know things have been rocky between Arg and Lydia in recent weeks after he relapsed in his recovery leading her to say she needed some time out from the romance.
Speaking to the TOWIE official episode, Lydia said: "I do feel like I am an iron lady and quite cold with it all but I think that's because what James tells me, what he will do moving forward, I have heard that so many times before. He constantly promises me things he will do but when I give him another chance he never follows through.
"I am enjoying being by myself right now and having time out. That might change because my emotions are still raw and I'm still very angry but he needs to just give me a lot of space because it's just too much pressure right now."
In emotionally charged scenes, Lydia had told Arg she was constantly hurt by his lies and deceit and she worried he would never change. "The fact you stand there and lie to me hurts me the most, that's the ultimate deceit. That will never change. You will always be a liar.
"When will you get it in your head you will run out of chances? You never think that. I have to realise in life I either have to live a life with you where you constantly let me down and constantly be deceitful or I choose tow walk away. What do you think is the most appealing thing right now? Why would I want that life for me?"
TOWIE airs Wednesdays and Sundays at 10pm on ITVBe.
