Married At First Sight star Olivia Frazer discovers boyfriend has a girlfriend after moving to Scotland

Married at First Sight star, Olivia Frazer, has issued a 'warning' in an emotional video with fans after she moved to Scotland to be with her boyfriend only to discover he already had a girlfriend.

The Australian reality TV star, 30, shared the video with her 189,000 followers on Instagram where she spoke about the shocking discovery she made about the unnamed man.

Olivia packed up all her stuff in Australia ‘for good’ and moved across the world to pursue a relationship with a man she met while travelling Europe.

After arriving in his tiny hometown in Scotland just two months ago, she said she noticed a change in her boyfriend’s personality.

Before she made the move, the man had been very attentive but suddenly became distant once she relocated.

Feeling alone and confused, Olivia didn’t know what was up until a chance encounter in a pub led to her discovering her boyfriend’s double life.

"The reason I've stayed in Scotland was to give it a go with a man that I've - yes, met in real life and have spent nearly every day this year speaking with and building something with," she said.

“I won’t get into the nitty-gritty here, but it turned out to be something really messy and cruel and I was led to believe it was something special.

She continued: "I've felt really embarrassed but I don't think I should be.

"I'm really proud of myself for putting myself back out there and being open to falling in love again and being vulnerable with somebody and it didn't work out... and that's really on him.”

Olivia told her followers she wanted to ‘put this out as a warning’ for anyone watching who might be struggling with something similar.

"I just wanted to put this out as a warning for anyone in a situation where there’s red flags, or your gut's telling you something feels off,” she continued.

Please don’t ignore that just because you want it to work.”

Olivia opened up further about the awkward encounter she had at the pub.

“I had no idea what to do, or what I’d done wrong and a lady in a pub then approached me and asked if I was still seeing him,” she told Yahoo Lifestyle Australia.

“I told her ‘ah that’s a bit complicated’ and she said: ‘Don’t. He has a girlfriend. Has had a girlfriend the whole time. You can you can do better, pet.’

She told the publication that the whole ordeal left her feeling ‘completely scammed and made a fool out of’.

Olivia continued: “We spoke almost every day since we met at the start of the year and he told me he wanted me to meet his son once I got back to Scotland, told me he wanted to give things a real go between us and made me feel so wanted after everything I’d been through after MAFS – but it was all lies.”
