The pair coupled up on launch night but only in the space of four days have had numerous ups and downs.
Last night saw tears when Jack said he'd partner up with Hayley.
But tonight, Dani says: “So the decision between me and Jack we made was I’m just going to give him a chance and see what happens in the next few days.
"But I am glad, I’ve sort of let my guard down a little bit with him. My nan would be basically saying to me ‘what are you doing Dan, stop being a div.”
She goes to chat with Hayley.
Hayley says: “I was just stressed because I feel like we had that conversation, then we played truth or dare. I was thinking ‘I love Eyal, I don’t see myself going any further with him than friends.’ I thought ‘well if I’m not happy with Eyal the only other safe option for me is Jack.’ Do you know what I mean?
"And for the last few days you’ve just been saying ‘we’re just friends.’ I thought ‘well, right now no one’s in here that I’m physically attracted to so I’ll just pair up with him and recouple with him and hopefully I’ll have my opportunity to find what I want in a man.
"Do you know what I mean? But then obviously after the challenge I’ve noticed you got upset. I don’t know what you were upset over.”
Dani explains her sudden U Turn with Jack - “It wasn’t about you. It was just ‘let’s just give it a chance, see what happens, get to know each other a bit more and I was like ‘yeah, OK cool’ and I don’t want you to think that I’m going back on my word because I just want to see what happens.”
Later, Jack and Dani have a heart to heart.
He tells her: “This is the happiest I’ve felt since I’ve been here. I promise you. Jokes aside. I feel like a weight’s been lifted. I do, I honestly do.”
Jack then leans in for a kiss, which is reciprocated by Dani, prompting cheers from their fellow Islanders.
Rejoicing over her and Jack’s moment of passion, Dani declares herself the villa’s answer to Meghan Markle: “We had a kiss and I felt like I just got married! Like when Meghan walked down the aisle and got married and that, I feel like that was me and everyone was cheering. It was lovely. “
Jack is equally overjoyed to have Dani back: “I tell you what, I’m like a Cheshire cat, I can’t stop smiling. It just felt nice and natural. I’m really happy and I’m excited now.”
Love Island 2018 airs tonight at 9PM on ITV2.
