Although he has been getting to know new girl Elma on a romantic level, he still feels a loyalty to single Anna, who he has a strong friendship with.
Anna and Anton speak about the situation.
Anna says: “I can see that you and Elma are getting on. You two look cute.”
Anton tells her: “I love you to pieces. My time in here without you wouldn’t feel the same.”
Anton later has a chat with Elma. He says: “I think the two of us are getting on really good. I like the direction it’s going. You’ve almost put all your cards on the table.”
Elma replies: “I think you’re a good person.”
Anton admits: “You’re making this experience how I imagined it would be in the first place.”
Elma reacts: “You always have tick boxes, the qualities that you want in someone. Slowly but surely those boxes are being ticked.”
Anton reflects in the Beach Hut, he says: “My heart is telling me one thing and my head is telling me another thing.”
Anton isn't the only Islander questioning his feelings tonight.
Joe finds himself having doubts about Lucie over closeness to Tommy.
It isn't long before the boys find themselves forced to face up to their feelings.
A text arrives in the villa to announce: “Islanders. Tonight, there will be a recoupling in which the boys will choose which girl they want to couple up with. #nomoreshapes #girlproblems #standbyyourman.”
With a recoupling on the horizon, Joe and Anton both have a lot on their minds but will they go with their heads or their hearts?
Love Island 2019 continues tonight at 9PM on ITV2.
As always on Sundays, the main episode is followed by After Sun with Caroline Flack on ITV2.
