The reality TV star and fashion designer, 25, admits she is devastated after discovering her beau had sent explicit texts to another woman.
However, she says he's '"not a cheat" and insists they are still together.
Bradley's X-rated selfies to 36-year-old Marie Asemota were exposed last weekend by the Sunday Mirror.
Now, in an interview with the same newspaper, Amy says JCB driver Bradley has begged her to forgive him and says the texts were "just banter".
Amy says: "What Brad has done is disrespectful.
"I am so upset and angry. We love each other but I can't have him around right now. I feel stressed and he has made me feel bad about myself. I've moved him out the house and chucked all his stuff out."
Amy, who has previously described Bradley as 'The One', adds: "He is heartbroken but he needs to realise what he has done to me and I can't have him around right now.
"And I know he loves me. I'm not paranoid about him now - I am just angry."
She and Bradley first began dating last year, although Amy only came clean about their romance back in May. The pair are thought to have met in a bar in Essex 15 months ago.
In August, Amy sparked engagement rumours when she was spotted shopping for diamond rings.
She even shared a photo on Instagram of herself posing in a Tiffany & Co sparkler...
But, despite Amy's heartache, it seems those wedding dreams aren't forgotten. She tells the newspaper: "Brad and I are still together. I'd like to think we'd still marry and have babies. I still think he's The One but he's got to learn his lesson."
