Following their time together on I'm A Celebrity last year, Spencer and Vicky stayed in touch and she openly admitted she 'fancied' the former Made In Chelsea star on her exit from camp.
Romance then blossomed between the pair when they were back on home soil and Spencer and Vicky enjoyed a string of dates together (including a brief trip to Monaco), before she decided to end things with him.
Appearing on Loose Women today, Vicky confirmed her reasons for cutting their romance short and revealed how Spencer reacted to her concerns.
While dating, Vicky made no secret of her worries about Spencer's womanising past. Speaking to Reveal, she admitted she had been 'deliberately standoffish' with Spencer because of it, as she was conscious not to be another girl that he ends up being unfaithful to - even if she does really like him.
Earlier this month, Spencer revealed he had been 'friend-zoned' by the 28-year-old.
He said he respected Vicky's decision, as it was a sensible one, and added on appearance on Loose Women soon after: "We weren't a couple... but I thought it was heading that way. She is a lovely girl. We came to the conclusion that our relationship could last a lifetime... were we just to be close friends and have each others back."
Sharing her side on the split earlier today, Vicky told her Loose Women panellists, Spencer had been truthful about the break up.
She explained at the end of their trip to Monaco, she decided the pair would be better off as friends. Vicky explained: "Spencer is a lovely lad. He's told the truth. That was exactly what happened. We weren't official. We were friends. We did try."
Vicky then continued: "I was honest and very open and I said that I liked him... but I like myself more. I don't just want to be another girl that Spencer Matthews cheats on."
She then revealed that Spencer then said to her: "I don't intend to cheat on you darling."
"Intend?!" Vicky recalled. "I spotted that loophole straight away mate. We decided to stay friends, he's a lovely lad, but unfortunately not for me."
