The MMC cheated because the OW made him think, not believe, think that the FMC was cheating with her male best friend/OM. The MMC did it to hurt the FMC but got caught in the middle of the act by the FMC. The MMC was forcing himself to do the deed and when it was interrupted he didn’t get any chance to get off from it. Not that I think he would have been able to with the way he acted, closing his eyes and waiting it out. Smh. Now let me breakdown the relationships here.
The OW Bianca is the FMC’s childhood best friend.
The OM Alex/Lex is the FMC’s high school boyfriend turned best friend.
The MMC has interrupted s e x (cheating) with the OW.
The FMC later has s e x (not cheating to me but definitely a poor decision given the circumstances) with the OM during her emotional upheaval. In essence giving him mixed signals IMO.
The OM, other than the one time s e x with the FMC, he never showed any real love interest towards the FMC through the whole book before and after the s e x. He basically said it’s just s e x and he wouldn’t mind some more. So his sudden interest after one round of couch Olympics made no sense. He never gave off the vibe that he was waiting for her. They were inappropriately too intimate for “just friends”, yes. But that sometimes happens when former couples stay friends after they end. Most people find it’s difficult to reset physical boundaries once you’ve been physical but his friendship should have ended when the MMC came into the picture.
The OW was made out to be crazy but this is never really explained as anything other than jealousy made her nuts, which is an extreme leap of behavior. How was she able to not show any of her crazy all her life, to any of these other characters, never mind to her closest relationship with the FMC, for years(!), but one day out of the blue she plots the destruction of the main characters marriage, stalks both characters, harasses the MMC with her delusions of their supposed future together or of everything going on around her, and ultimately kidnaps a baby with no plan on what to do after that. Other than to go to some random neighbors house who she barely was friends with claiming to be babysitting.
This story was all over the place. It had no real resolution of the cheating by the MMC. He needed therapy. Because his reasoning to have s e x to actively hurt his wife is another extreme reaction from being told and shown flimsy evidence that the FMC was having an affair. Who does that? Immature people, maybe. The MMC was described as a 34’ish mature, respectful and rational person before and after this confrontation. So it really was out of character. If anything he would have confronted his wife before sleeping with anyone. He would have plotted an out before letting the FMC know that he “knew”. It would have been more sneaky or in your face but not outright sleeping with the OW who he had been thinking of all the things he didn’t like about her during her “reveal” of the FMC’s supposed infidelity.
The author did have the hard questions asked through most of the original part of the story. Like the FMC asking the MMC, “had she ever given him a reason to believe she would cheat(?)”, or be the kind of person to have an ongoing affair and lie to her spouse indefinitely. Or later, when the FMC’s sister asks her when does sleeping with someone else while separated from your spouse for cheating make it a tit for tat option?? More of this happens but then the main couple just decide to be together and then nothing else is said or done to work on the betrayal.
It was all squared away as the OW was crazy and it was them against her. The OM honestly had my sympathies because he got caught in the middle of all of their roller coaster of drama and then he was kicked to the curb like it was somehow his fault. Yes, he had s e x with the FMC when I don’t think he should have, but he is a dude and from everything described of all these characters just as self centered and he chose the easy s e x. It absolutely wasn’t cool. But he was only 50% to blame at best. He was also jerked around by the FMC whenever she needed him. He dropped everything for her, his best friend at every pivotal moment. So I feel the indiscretion could have been forgiven in time.
But with the OM, I felt the FMC wanted to keep him friend zoned so that she always has a man she is intimate with who is always there. Not just sexually either. The FMC was absolutely having a type of emotional affair with him for years. He was sort of her fallback relationship. Whether they had s e x or not is irrelevant. They were actively acting like a couple with each other more than just friends. I think the FMC was the OM’s fallback too from the way they played out on page. It’s never explained why they were even “ex’s for a reason”. What ended their relationship? Why couldn’t they work before or in the future? Besides the obvious love between the main couple that is. It does come off to an extent, that if the MMC wasn’t in the picture and the baby had turned out to be the OM’s, then they could have worked out in time.
Anyway, I feel this book sort of lost the plot of the “cheating” and made all about the crazy OW. The main couple did next to nothing to recover from the cheating but did everything to act like it never happened. Brushing it under the carpet. The story did hold my interest because it was trashy goodness but it was not emotional outside of the caught in the act scene at the very beginning of the story. There was a huge amount of errors that even a novice editor should have caught so it made reading crazy a bit more difficult. I don’t know if I would give this author another chance though. Good luck.
