Sources close to production tell TMZ ... when 'BiP' wrapped in June, several cast members warned Josh that Nick portrayed him as the villain for stealing away Amanda Stanton. Our sources say Josh felt blindsided by the bad blood but wanted to make things cool with Nick, so he reached out to him before the show aired ... but Nick never responded.
Sources close to Josh tell us he feels Nick seized the opportunity to play the role as a "victim" and feels that he won over Amanda fairly. When Josh first arrived at the house, he asked the girls if any of them were in a serious relationship ... and Amanda said no. However, we're told the clip didn't make the cut.
After seeing the drama unfold, we're told Josh feels it's now too late to ever respect him again.
Now that's tough love.
