"No, honestly, at this point, I'm past trying to work it out," Blake, 33, toldUs Weekly on Sunday. "I've tried multiple times, but it's impossible with him."
Blake said, "The dude just does not like me," and claimed he has no idea why the Season 21 The Bachelor star has such an issue with him.
"It's been years. I've just given up at this point. So yeah, it is what it is," Blake noted.
Nick and Blake's feud dates back to Summer 2019 after Blake appeared on Bachelor in Paradise's sixth season and was accused of being a playboy and womanizer.
Prior to his stint on Bachelor in Paradise, Blake had slept with both Caelynn Miller-Keyes and Kristina Schulman only one night apart at the Stagecoach music festival in April 2019 -- and Blake was on the beach with both women at the same time when filming Paradise.
Caelynn alleged on Season 6 of Bachelor in Paradise that Blake had ghosted her and ended their "exclusive" relationship, calling her "a mistake."
Caelynn also accused Blake on the show of being "scum" and silencing her because he didn't want anyone to find out about their relationship.
Blake denied all of Caelynn's allegations and released personal and private text messages he had with The Bachelor alum in August 2019 in attempt to prove they had mutually agreed their sexual relationship would just be a fling.
Caelynn said she felt "absolutely mortified" over the text messages being made public.
"I am not here to deny those text messages or the conversations that took place. Things got taken out of context on the show, and a large part of the story is missing," Caelynn wrote on Instagram in August 2019.
"The reality of the situation is that Blake was not a one night stand at a music festival and the... text exchange that Blake chose to share is not an accurate representation of our past relationship."
Blake subsequently apologized on Instagram, admitting he had made a lot of mistakes with women and felt ashamed and regret, but he said he had "no choice" but to release the private texts with Caelynn because she had attacked his character and his name on Bachelor in Paradise's sixth season.
"I know by talking to a lot of people over the weekend that Blake admitted, 'I know that she is going to look bad,'" Nick reportedly claimed on an August 2019 episode of his "The Viall Files" podcast.
"I know that he threatened people about releasing these text messages for months in anticipations coming up, which makes it all that more premeditated. Then he ended up deleting it when it got really nasty, but it's not like he didn't realize."
Nick believed that Blake was trying to spin a narrative and manipulate the public's perception of him.
"It was more important for him to try to change people's opinions back to like, 'Oh, Blake is just a sweet boy... This was just one weekend where he got a little drunk and had a little bit of sex.' No, he's been, like, f-cking like crazy for an entire year," Nick said.
Nick's judgment apparently angered Blake, who said he'd never be a guest on "The Viall Files" and had no desire to hash things out with Nick.
"I'd rather sh-t in my hand and clap," Blake, who is now happily dating Love is Blind alum Giannina Gibelli, reportedly said in April 2020.
Blake isn't the only person from Bachelor Nation who has something against Nick.
