Married at First Sight UK star Lacey Martin has spoken out for the first time since her split from Nathan Campbell.

Reports recently emerged that the pair had separated after the reality show's season nine reunion. Nathan confirmed the news earlier this week, claiming it was Lacey's "decision to part ways" and saying he has "nothing but love and good wishes for her".

Lacey has now opened up about their split for the first time during a new interview with The Sun, where she claimed that Nathan "blocked" her after she called him out for not supporting her Race For Life fundraiser.

"I genuinely didn't think he would do this to me. What we had was so real and special," she said.

"Nathan always used to say to me, 'Oh, this is the relationship I've always wanted', in terms of always laughing together, always dancing together. I could be my full self and he could be his, and I accepted him for him."

What to Read Next

The reality star went on to share that, since Nathan has ADHD, she researched the condition and how it affects relationships in an effort to strengthen their bond.

"He's never had anyone, from what he told me, that's really gone above and beyond," she continued.

"And I just feel like, what thanks do I get? He's just blocked me, like I'm nothing, and that's what really hurts.

"I did try and make Nathan realise that when I've tried to reach out, like, even the strongest couples argue, but to completely withdraw and block me has broke my heart because despite our relationship, we had a good friendship and I just felt like I didn't deserve how he treated me."

Lacey said that she is now "focusing" on and "pouring the love" into herself, adding that her "mental health has gone really bad since this relationship because he was my best friend".

"It's like you're grieving a person that's still alive because you went from 100 to zero, basically," she continued.

"I'm sitting here crying because we had such a good relationship and genuinely had feelings. And I feel like if you genuinely love someone, why would you want to let them go? Like, you would fight.

"I just feel like I don't recognise him anymore. I'm just hurt because I just feel like he didn't appreciate me in the end."
