But his dad Mark has now reassured viewers of the hit ITV2 show that his feelings for Liberty are true because he wouldn't have been able to come up with a game plan.
Speaking to Bristol Live, Mark said: "It's quite an emotional thing to see your son struggling.
"The worst thing about it for us is seeing the vile comments – mainly from keyboard warriors that don't understand Jake.
"They just see him on the telly and think that he's in it for the money or he's a bit of a, you know, bit of a snake and you know, I'm not being horrible to Jake but he's not intelligent enough to have a game plan!
"It's quite hard to stomach the comments that people write, it's not nice when he hasn't done anything wrong and it's just the way he has been made to look."
Mark also questioned whether Liberty's fellow female Islanders were told by producers to act the way they did when she shared the news of Jake telling her he loved her.
He said: "I don't know whether some of it is being staged or not because when Liberty came back onto the sofa, not one of the girls reassured her that he may have said what he said because he actually loves her. They may have been told to react like that.
"Hopefully we have turned a corner after the weekend and the public will start thinking that the others are in it to win it too."

"Jake and Liberty have been strong from Day One and I think the others felt it was a good idea to get rid of them, so they had a better chance at winning the show."
Mark also admitted that Jake's family have considered pulling him from the show as they are concerned about his welfare after the villa.
"Mentally-wise, I don't know what he's going to be like when he comes out and I just want people to send out positive vibes for him.
"For us, it has just been uncomfortable to watch these last few episodes but hopefully we can move on and we have got through the worst part of it.
"At the end of the day, we are really proud of him and we are looking forward to meeting Liberty when they get out.
"He's just gone in there to have a great time and a wonderful experience but he's being portrayed as a villain, which is hurtful because that's not Jake at all."
