To figure out what happened, Micah met Max to get the truth out of him.The minute Max met Micah, he broke down, revealing that he had messed up. He then said,"I have this good buddy of mine that's a good bit older than you and I. We were kind of celebrating his retirement at his place and he invited his lady friend over that I knew he liked. And so I was trying to be his wingman. And so I took things a little too far. I was just flirting with her, and that led her to think that it was okay to try and kiss me, which she did."Micah was taken aback by the confession. He shared that he was disappointed in Max and never expected him to do such a thing. Max also added that he told Moriah immediately. He regretted telling her that he was proud of himself for not taking it further.Hearing what Max did, Moriah broke up with him instantly. But their argument continued as he said some hurtful things to the Welcome to Plathville star. He also commented on how she dressed, which only worsened things.
