#2 Rusev defeats Lashley and rejects Lana

There hasn't been a single time since this storyline began that has seen Rusev get the upper hand on Lana and Lashley. The night in which the new couple revealed themselves together in Lana and Rusev's bedroom, he did ruthlessly attack Randy Orton and Baron Corbin, which was a bit of a victory for Rusev, but that was only the second week of the story, and we're 6-weeks in! Not only that, but it wasn't revenge on Lashley. He did get a hold of Lashley and knocked him down a few times, but after being distracted by Lana, Bobby and his new girl wound up standing tall once again.
It's been a brutal return for Rusev. He was gone for a full 4 months, and only 2-weeks after his return, which appeared to involve a move toward the top of the card on RAW, the Lana-Lashley bombshell was dropped on him.
How could Rusev possibly forgive his wife? Based on his complete lack of response when Charly Caruso asked him where Lana was, it seems apparent that during his 4-month hiatus there was some trouble in paradise that led to this entire situation. If Rusev isn't in the wrong here and didn't cheat on his wife, and Lana is only doing all of this to torture Rusev for something that she perceives as a wrongdoing by her husband, why should he take her back?
I can imagine that Rusev may finally get his revenge by beating Bobby Lashley in very convincing fasion at Survivor Series, after which Lana tries to reunite with her husband. He refuses because she has been tormenting him for no reason for months, regains a little bit of dignity, holds his head high, and moves on with his life and his career.
