In tonight's episode, the Married At First Sight 'star' opens up to Roxanne in a chat on the beds.
Ben declares: "I love you, you’re amazing, I’m sorry."
Roxy begs: "Shhhh"
But Ben continues: "I don’t care any more, I thought today, I thought f**k it.”
Ben adds: "It’s how I feel, f**k em’"
He then continues: “I don’t know, I know how I feel, it is what it is, end of."
Roxy reacts: "I can't believe that you just said that."
Ben says: “I’ll stay away from you...
"I finally find my soulmate and like, I can’t even talk to her without people thinking, uh, he’ll ruin her life."
The chat comes just a day after Ben also claimed to have feelings for Roxanne's fellow housemate Gabby Allen.
In last night's show, he told Big Brother of the Love Islander: "She's a bit standoffish which I like, but then all of a sudden when that little twinkle comes... she's got a little sense of mischievousness which I like.
"I'm buzzing off that, I'd love to develop something there and sometimes, I'll be honest, I'm going to say it as it is, I don't want to come across as a big head, but I see her look at me sometimes and there's a little something there."
Ben continues: "And she puts me on the back foot a little bit, and I like that. I like to be put on the back foot.
"I don't think she knows where she is or what she is and I'm a bit like that I suppose."
Elsewhere in Wednesday's episode, Roxanne admitted: "I'm scared to go out but I don't know what I'm scared of."
Jermaine Pennant replied: "You don't know what you're going out to. Is your family or your missus or anyone going to be fuming? Is there backlashes when you come out?"
Roxanne added: "It's concentrated in here. I hope my fella understands... I was on the fence about this. He was the one that was saying 'Do it, do it!'"
