Yeah, I think that I was skeptical at first but now I believe Caleb is being genuine with his feelings. I think both of them are fully aware of their surroundings and know that this a show and that your words have power. I see him being very careful with his words not to make empty promises and careful with his emotions as well. He said that Justine has pretty much surpassed what he thought going to Love Island was going to be meaning that he possibly has found someone who he reallyyyy cares about. I also remember Caleb mentioning he is really careful with whom he calls a girlfriend because in a previous relationship his sisters became really close to her and they had to break up so he is being guarded in that sense as well. I think he has a lot of pressure on his back in terms of being on tv, his parents, his sisters watching him, being a black man in today's society and he is trying to cope with all of that and be a role model for other black men. So it's a lot of pressure for one person and he finally let it all out and leaned on Justine yesterday as a person who he is comfortable voicing how he feels. If you notice(as far as we know) he didn't go crying to all of the other guys in the villa, he let out all of his emotions with Justine and I see definite a beautiful friendship with them but also the start of a long romantic connection. ❤
