Your wife seems like the type of person who enjoys proving she's right,and others are wrong.
She's very defiant. How DARE you ask her to look at the hotel's camera footage..such outrage.
If it wasn't her..if she wasn't in that room,with that man,all night, you better believe she would jump at the chance to prove she didn't do it,and feel superior, and rub your nose in it. And the hotel staff? Man,if I were in her position, and they told my husband what they told you,and I was innocent? Trust that I would be RUNNING down there, to watch the footage with all of them,and my husband, so I could prove them wrong. I would be LIVID that staff told my husband I spent the night with some man. I would demand an apology, and I'd want to speak to the general manager. If wrong, they falsely accused me of something that was hurting my husband, and could possibly cost me my marriage,and time with my kids.
If I was innocent, trust that I wouldn't be laying around,playing on my phone.
Her refusal to ease your pain, should be a deal breaker. It's cruel.
But..she's guilty. She knows it. You know it. We know it.
Stop begging for the truth. Her inaction is an admission.
