Gemma, 34, told the TOWIE official website that she thought she'd found happiness with the man, who she does not name, only for them to break up and her to find herself single again.
"I'm definitely looking for love again," she told the website.
"Obviously I went through a terrible time, a sad time. I met someone who I thought was the love of my life. I was planning to have a baby next year and it's all gone wrong. But is it fate? I'm back in Essex now, hanging out with Bobby and looking for boys."
Gemma left Essex for Australia last month to appear in I'm A Celebrity... Get Me Out Of Here, but lasted only three days in the jungle. She later admitted her head hadn't been in the right place following an alleged attack involving her then-boyfriend before she flew to Oz.
She has not spoken of her ex-boyfriend publicly.
Her early exit from the jungle meant she was back in Essex just in time to film the Christmas special, which airs on ITVBe this week.
Gemma admitted it was "nervewracking" rejoining the cast and crew for filming, but added: "Being back, I have a rush through my veins. TOWIE is in my blood!"
She added that being away in Australia, albeit briefly, had made her appreciate home, friends and family even more.
The Only Way Is Essexmas airs Wednesday, 10 December at 10pm on ITVBe.
