Poole flew out to Dubai last week following reports that Terry had cheated on her with model Vanessa Perroncel, the former partner of his England team-mate Wayne Bridge. Her decision to leave the country sparked rumours that she wanted a divorce.
However, according to the Daily Star, the 28-year-old has told friends: "I am not divorcing John. We have known each other since we were kids - and nothing will shake our marriage. I am standing by him 100%."
Poole, who has 3-year-old twins with the footballer, is said to have added: "I am in Dubai with the children now to protect them from the media.
"But I am talking and texting John all the time and sending him pictures of the twins. John and I love each other very much. Every marriage goes through turmoil and this is no different. We will be together for ever no matter what life throws at us."
Terry is expected to join Poole in Dubai for Valentine's weekend later this month.
