Mike Thalassitis’ manager says the star’s break up with Megan McKenna "hit him really hard".
Dave Read claims Mike – who was found dead in woodland near his home aged 26 earlier this month – was "very down" following his split from Megan, after they dated for seven months, and Dave says the 26-year-old beauty was the former ‘Love Island’ star’s "first proper girlfriend".
In an interview with Now magazine, he said: "I don’t want to pretend I know all of Mike’s medical history because I don’t.
"But I will say that he was very down after he split from Megan McKenna.
"He openly admitted that he had really fallen for her. She was his first proper girlfriend and, although he’d dated other people in the past, it was the first time he’d fallen in love.
"The break-up hit him really hard and he was down for a few months."
Megan recently confessed she’s still "trying to come to terms" with the death of Mike.
She wrote on Instagram: "Sorry I haven’t been on social media but I’m in complete shock and trying to come to terms with this.
"I can’t believe I’m even writing this post.
"My thoughts and prayers are with Mike’s family. Rest in peace Mike. X (sic)"
Megan’s comments come after several former ‘Love Island’ stars took to social media to pay tribute to Mike.
Kem Cetinay and Amber Davies, who won the 2017 ‘Love Island’ series which Mike competed in, led tributes to him.
Alongside a broken heart emoji, Kem wrote: "Such heartbreaking news. My thoughts go out to all of Mikes friends and family (sic)"
In her own post, Amber added: "I am in utter shock. @MikeThalassitis you were one of the most genuine guy! I just can’t believe this! You’ll be missed so much you have no idea (sic)"
