What's the Name of That Book??? discussion

The book is not "The Perfect Marriage" despite the plot sounding incredibly similar.
I'm not posting and spoilers as far as I know because I didn't get that far into the book. I don't remember any names, sorry!! I believe the book takes place in the 2019, but it's definitely 2015+
The book reads from 3 perspectives: Mistress (only at the beginning of the book), Husband, and Wife.

The book starts from the perspective of the mistress. She has sex with a married man and they get into an argument about him not leaving his wife. The man leaves so she takes a shower, she hears someone come in and thinks it's the man, but it's someone else that ends up murdering her.

She's supposed to go on a business trip (I think it was later that same day) and the driver she booked to take her to the airport has an uneasy feeling about her not answering her phone so he goes into her apartment and finds her dead.
Side note: The mistress is a young adult and she has a cat. I think the driver described the cat having blood on it while he was waiting for her. I believe she also lived in Portland.

Man gets home and police show up on his door to take him to the station for questioning about the murder of his mistress. His affair is uncovered.
When the wife finds out, she doesn't believe her husband committed the crime.

The wife and husband have twin boys together and they work for the father of the wife. It's a large company and the wife comes from wealth. The husband was using company funds disguised as work meetings to travel from Texas to see his mistress.
Wife's parents show up at the house with their family lawyer for damage control. The wife's parents have never been a fan of the husband in general.

The book goes into details about the husband having met his mistress at a coffee shop while he was on a real business trip. I don't remember much else about the description of their affair aside from the mistress being irresponsible with money. The husband found her unpaid bills and he wanted to help her with them, but she got mad when he tried to bring it up.
I think she was getting by with a sugar daddy kind of situation before having met the husband?

The wife decided to take yoga classes and ends up falling for the yoga instructor. They hit it off and they want to sleep together, but they decide to wait until she serves her husband divorce papers. She had them drawn up and ready to go, but all hell broke loose with the murder so she decided that wasn't the right time.
The yoga instructor owns a small bar in town and after the husband's affair had been uncovered, he drove to the bar and found his wife playing darts with the instructor and caused a pretty big scene.

The last things I remember:
The wife travels to the apartment where the murder took place and breaks into the property where a police officer that's investigating in her hometown catches her and tells her to gtfo. While she was in the apartment, she discovers her husband had gifted the mistress a necklace that he had gifted her for the birth of their twins.
After she gets kicked out of the apartment, she decides to talk to the next door neighbor. The neighbor is an older lady that gave the wife some information on the kind of person the mistress was.
As she was leaving, she gets a phone call or a text from the actual killer telling her to leave it alone and confirming her husband isn't the actual killer.

The husband gets drunk and drives their SUV to the bar and he ends up getting arrested again cuz he's a reckless idiot. It was implied that he had the murder weapon in his center console.

Megan, did you read this book around 2019?

Neither of those. Ty for the suggestions!

I think Heggan Christiane has a book with this plot. I just can't remember which one.

I took a look through the book descriptions and it doesn't look like the book I'm looking for is among them.
Thank you for your input!

I finally figured it out. Whew!
