There have been a couple of red flags that my wife may be cheating on me...

The house is empty this week because her kids are gone on vacation with their dad.

I came home Monday night and the bed was askew. I asked her about it, saying, "what have you been doing in here?? " she played it like it was weird, but she didn't know how it happened. Edited: She was just coming out of the shower, which I thought was weird. Why is she showering at 5pm??

Later that night, I initiated pretty hard, and she was COMPLETELY unreceptive... Which is very out of character for her. She is usually the higher libido of us. Normally, she'd at least say, "I'm really tired. Can we postpone until tomorrow?" But she didn't give me anything. Just laid there like she was dead. I gave up and went to sleep.

This week, I've tried to initiate a couple more times and same thing. She's not receptive. Especially with an empty house, she's usually all over that because she loves to scream.

I checked the cell phone records and there are a few texts from numbers I don't recognize, but usually only like 4-5 of them spread out over several days. I would expect an affair to have many, many texts.

Am I just reading things into this where nothing really exists, or is this cause for concern?
