Former glamour model Nicola announced she had split with former footballer Tom in August after he was accused of having an affair with an American waitress in Las Vegas.
Last week, the couple were spotted out together in a London bar, however Nicola is adamant that she is not prepared to take him back - adding that she is looking for a new man.
Speaking at a birthday party held for celebrity jeweller Vashi Dominiguez, Nicola, 33, said: "There is no going back for me - the marriage is dead. He killed it by what he did in Las Vegas.
"He says he has made the biggest mistake of his life and has pleaded with me to take him back [but] what is done is done.
"He has treated me appallingly and I just don't feel the same way about him as I used to.
"We had such a great marriage and two lovely boys but I just don't feel the same. Part of me will always love him but I cannot be his wife any more. We will always stay friends for the sake of the boys."
Nicola wore a cute black shorts and a camisole to Vashi's birthday party, which was held in London's Mahiki nightclub, and it sounded like a pretty impressive night. Apparently, Vashi gifted guests with jewellery from his online range Vashi.com, totalling a staggering £150,000!
While at the bash, Nicola also confirmed that she is moving on from her marriage breakdown and has even begun looking for love again.
"I'm going out and having fun and meeting some fun men. Life goes on - I'm not going to stay at home moping," she explained.
Former I'm A Celebrity...Get Me Out Of Here! star Nicola married Tom in June 2009 and they have two sons together, Rocky and Striker.
Speaking in the aftermath of their break-up, she told Reveal: "Everyone sees me as a strong, hard-faced bitch, when actually I'm just an insecure girl who wants her marriage to work.
"I'm not perfect, but I've been 100 per cent faithful to my husband, marriage and children, and I can take that away from this."
