The pair are said to have grown apart in recent weeks, with a source close to them claiming their six year age gap became a problem.
Wes has moved out of their shared London home in the wake of the split and has reportedly moved in with fellow Islander Josh Denzel.
A source told The Sun, “It's all over. They started to grow apart and the age gap became really noticeable between them.
"They want to remain civil with each other and hope to remain friends.
“There’s been no funny business, no cheating or anything like that, it’s just fizzled out between them."

Love Island stars who have recoupled outside the villa slider
Yewande Biala and George Rains

Kieran Nicholls and Chloe Crowhurst
Lucie Donlan and Joe Garratt
They (not the public) branded themselves as 'Juicy' but when Joe Garrett was booted from the villaviewers were shocked that Lucie Donlan didn't follow him.

Weeks after the Love Island 2019 final and Lucie and Joe confirmed on Instagram that 'Juicy' was back together.
Arabella Chi and Wes Nelson
Arabella Chi was mugged off by Danny Williams who appeared to be devastated when she left the villa but he quickly bounced back with Jourdan Riane. Luckily the model got over him with Love Island 2018 finalist Wes Nelson and she was recently slated for 'PhotoShopping' a photo alongside her new man.
Jon Clark and Chloe Crowhurst
If you cast your mind back to Love Island 2015 you'll remember when Jon Clark famously proposed to Hannah Elizabeth. It didn't last (bless them) and he went on to star on TOWIE. Fast forward a couple of years and he dated Chloe Crowhurst but after the Love Island 2017 line-up was announced he publicly slammed her and revealed they were dating. After she left the villa they briefly reunited before calling it quits.
Jon Clark and Elma Pazar
Okay so this one hasn't actually happened but Jon Clark apparently has his eyes set on Elma Pazar. We don't blame him tbh, she's an absolute babe.
Kem Cetinay and Kendall Rae-Knight
Days after being the first dumped Love Island 2018 star, Kendall Rae Knight was apparently spotted kissing 2017 winner Kem Cetinay. Although Kem insisted they're just friends.
Niall Aslam and Rosie Williams
Charlie Frederick and Lucie Donlan
Charlie Frederick didn't get the best of chances in the Love Island 2018 villa; he was partnered with the iconic Hayley Hughes but they were quickly dumped. When the 2019 series started Charlie slammed Lucie and said she's "most definitely not looking for love". Lucie didn't take it lightly and clapped back at him.
Charlie Frederick and Arabella Chi
Charlie also got with Arabella before she entered the villa. He actually claimed that the model was a 'liar' and hinted they were still dating even when she went into the villa. After being booted from Love Islandshe branded him an 'idiot' and said they had blocked each other before she went on the reality show.
Kaz Crossley and Theo Campbell
We really thought Kaz Crossley and Josh Denzel were going to last but alas they didn't. A few months after announcing their split Kaz announced on Instagram that she moved on with 2017 legend Theo Campbell. They since shared cute snaps on social media.
Jess Shears and Dom Lever
So Jess and Dom were happily coupled up in the villa but when the boys voted for her to leave they were both left devastated… Dom wasn't that upset though because he didn't follow her. Then there were reports that something went down with Mike Thalassitis but after Dom left Love Island he reunited with Jess, the pair got married and are set to welcome their baby into the world this year.
Sam Gowland and Amber Davies
Love Island and Geordie Shore fans were stunned when Chloe Ferry claimed that her ex-boyfriend Sam cheated on her with Amber. Dramz. Sam and Amber have both denied the accusations but Chloe has insisted they're true.
Wes Nelson and Amber Davies
In January 2019 following all that Dancing on Ice drama with Vanessa Bauer, Wes Nelson and Megan Barton Hanson split. However a couple of months later there were reports that Wes had been 'sexting' 2017 winner Amber Davies. Then on Celebs Go Dating, Amber claimed he had been messaging another Love Island star before she appeared to brand Amber a "snakey b-tch" on Instagram. Following the whole Amber/Sam allegations, Megan wrote: "Imagine moving like that and lying to numerous heartbroken girls that you ain't sh-gged their ex!"Amber denied the rumours in an emotional tweet.
Eyal Booker and Kendall Rae Knight
Tbf, these two did share a little kiss on the main show, but then things got hella steamy and a little weird tbh in the reunion show when they snogged in a swimming pool. Nothing long term came of it.
Ellie Brown and Michael Griffiths
Michael and Ellie got together during MTV's Celebrity Ex On The Beach. They both said they were single as the show ended but then posted cute pictures together on social media. However, that came grinding to a halt when Michael started posting cute pictures with other women too.
Rebecca Gormley and Biggs Chris
Beauty queen Rebecca chose to couple up with Jordan Waobikeze instead of Biggs in the Love Island villa, following her failed romances with Connagh Howard, Wallace Wilson and Luke Trotman. She clearly regretted her decision though as she coupled up with Biggs just weeks after being dumped and returning to the UK. Despite cheating rumours on both sides, they're still going strong.
Luke Mabbott and Lucie Donlan
Romance blossomed for the couple in summer 2020 and they 'confirmed' their relationship status when they shared the same photo (of a hot tub) to Instagram. As is the modern way.

Jess shared a number of photos of her posing in lingerie but it was the caption that got fans talking as they thought she could be hinting at a pregnancy when she wrote, “Undressed. I predict a baby boom in about 9 months.”
“Taking to her Instagram story, she told fans, “I just thought I would come on here, my last post everyone thinks that I’m taking offence that I was asking for people to think I’m pregnant because of my caption.
“I’m not pregnant and I didn’t expect people to think anything other than I think there’s going to be a baby boom in nine months.”
