A day after Monday's episode featured an emotional moment between her and her ex-husband Jeremy Calvert over drinks at dinner – in which the tearful mom of three revealed Calvert was the "one person" for her – Messer slammed the MTV series as a "fake ass show" and wrote she was "99.9 percent sure those feelings were mutual."
"Leah wrote that because the show cut out everything on Jeremy's side," an industry source tells PEOPLE. "He was the one who was begging her to come back and to give him another chance. He was the one that coordinated the date and to try to make it work."
"The show was edited to make it seem like she was the one doing it and didn't show anything about Jeremy, and she wanted to set the record straight," adds the source.
I'm 99.9 % sure those feelings were mutual. I could go in detail, but wont. Oh, how I love this fake a#% TV show. #SoOverIt— Leah D. Messer (@TM2LeahDawn) April 19, 2016
Meanwhile, this week wasn't the first time Messer, 23, blasted the show for allegedly manipulating her footage.
Last month, the reality star went on an explosive Twitter rant against the network after the season premiere featured her daughter tearfully shouting that she didn't "trust" her mother, complaining that she never gave them food in the morning.

"It's so sad how the person behind the editing can even live a happy life by editing to manipulate the audience watching. It makes me feel like my story just isn't enough," Messer wrote in response to a fan's tweet asking why she continues to film the show despite being "bashed."
"It hurts to feel BETRAYED by the ones I THOUGHT I could trust with my story. It goes to show you how 'THE ENTERTAINMENT WORLD' really is," she went on. "I hope to continue to share my story but I REFUSE to allow it to be twisted for the benefit of a NETWORK!"
