Newport-born Liam will give his first live interview after leaving the Love Island villa on Friday.
On Friday's episode of the ITV dating show, the 22-year-old gathered everyone around the fire pit.
The Welshman told his fellow islanders that "he wasn't feeling himself" and that he hadn't "been giving 100%."
Liam added: I'm miles off that and I've been having a hard time finding that.
"I've made the decision that I am going to leave the villa.
"I've been thinking long and hard about this decision, it's not a spur of the moment thing."
Liam to make first live interview on Love Island's After Sun
The shocking revelation came after Liam, who was originally coupled up with Michael Owen's daughter Gemma, became single after Italian bombshell Davide Sanclimenti coupled up with her.
Viewers were looking forward to Liam making connections with the new girls Afia Tonkmor, 25, and Ekin-Su Cülcüloğlu, 27, who he got to go on a date with on Thursday's show.
The Masters student had previously shared that being alone in the villa would be his worst nightmare.
After he saw his nightmare come true he shared: "Everybody wants to feel wanted don't they, so I've put myself in a position now where I could not be wanted and it's going be all eyes that.
"Probably not being wanted in a recoupling or something like that. No one wants to be last one do they, no one wants to be the last picked."
