The fashion designer broke up with Lockie on the first episode of TOWIE's new series after saying she couldn't handle the way he treated her anymore.
She later learned from Chloe Sims that Lockie had wanted to pop the question in Marbs and even had an engagement ring with him during the moment she said they should split.
Speaking to the official TOWIE website, she said: "Obviously I feel guilty because it's not a nice thing he was thinking that and I split up with him but at the same time we did used to talk about marriage a lot and kids and all so in that sense it's no real surprise.
"But it's a bit of a shock he was going to do it out here."
She added: "It's not even about winning me back. It's him proving to himself he has to change. He knows what he has to do. He has to change and sort himself out."
Lockie said he'd move out of the flat once they returned to Essex but has remained hopeful they can work out their differences and be together in future.
"I think we will get back together. I know I love her and she loves me. I think I can change her mind if I do the things she asked me to do, if I sort myself out. It's my fault. It's me who caused this with my mood swings and stuff. I think we will get back together one day and if all goes to plan we could have an engagement very soon."
TOWIE airs Sundays and Wednesdays at 10pm on ITVBe.
