Speaking to The Mirror, the 29-year-old reality TV star said that she would never rekindle her relationship with Reid. Houghton added that she suspected the 37-year-old cage fighter was still in love with his ex-wife, model Katie Price.
Opening up about her relationship with Reid, which ended in June this year, Houghton said: "I finally got to the point where I had to get out, and I could never go back. Now I don't believe he ever really loved me. But at the time, he would tell me he loved me and of course I believed him."
She continued: "I know right now that this is a really, really hard testing time of my life. Climbing into an empty bed every night is a horrible reminder."
Houghton also described Reid's relationship with their daughter, four-month old Dolly, explaining: "She was only two months when we split, so I haven't really seen him be a dad.
"But he is her dad and always will be. I will not stand in the way of them getting to know each other. But it is hard when he comes round and I see him playing with her because we were meant to be a family."
She also revealed that Reid kept notes detailing his relationships with Price and Houghton. She said: "He had written all about me with bullet points about things that had happened, things we had done. I cleared out my flat last week and I found one he had done on Kate as well."
Following their split, Reid released a video publicly apologising to Houghton, who has previously claimed that Reid was plotting against her.
