Tearing up to her co-stars, Marnie said: "Obviously we have fallen out before, but my god, I have fallen out with him now. I will never speak to Aaron now."
She continued: "Honestly, the amount of anger I have got built up inside of us, I don't think it is f**king normal. I've got so much f**king anger and I hate him so much for doing that to us.
"He could have had the decency to come over and tell us [he was leaving]."
Aaron decided to leave the series after learning Marnie is bisexual from his co-star Nathan Henry. It was the last straw for Aaron, after he and Marnie had continuously argued since making their relationship official.
While he stressed he didn't have a problem with Marnie being bisexual, Aaron was angry that Marnie had continued to kiss Chloe Ferry on nights out when she had promised him she wouldn't do so. After hearing Nathan's confession about Marnie, Aaron then likened her drunken kisses with Chloe to 'cheating' and claimed his head was "all over the place."
He left the club without telling Marnie and packed his bags and left before she returned to the villa.
Reflecting on his exit the morning after, Marnie admitted: "Honestly, the amount of anger I have got built up inside of us, I don't think it is f**king normal. I've got so much f**king anger and I hate him so much for doing that to us. He could have had the decency to come over and tell us."
Nathan apologised to Marnie for telling Aaron her secret before she did, but she insisted she didn't blame Nathan for her problems with Aaron.
Marnie said: "He knows I've been with girls, he's known for a long time. I don't blame you for anything, in fact, I blame everything on Aaron." She added privately: "I never thought he would leave and give up on us."
The gang then headed to Kavos and Marnie insisted she wasn't going to "hold back" when it came to pulling other boys on their night out.
She said: "I think I might actually go on the pull tonight. I'll never be the same with Aaron after what he did to us. Walking out on us because he found out such a big thing and not even talking to us first!"
Although, she did later admit that she couldn't go through with it.
While Aaron and Marnie did appear to pick things up after filming for the series finished, things didn't work out... again. Marnie is now dating CBB star Lewis Bloor and Aaron has revealed he and Marnie are no longer speaking.
Geordie Shore continues Tuesday 22 November at 10pm on MTV.
