<human>: Can you condense the text into a few key points?

Long time lurker, first time poster.. was using wifes iPad the other day and noticed there was a photo of her from the chest up with one of my guns pressed against her taken while I was at work one night.. this photo was not sent to me. Thought it was weird. Moved on. Next day; go to work, come home, on iPad, another photo appears, this time up her skirt she wore to an interview that morning. This photo was not sent to me either. Not sure how to approach this.. this happened once before and her excuse was she took it for me but didn't send it because I said I don't like to get pictures like that on my phone. Which is true, I did say I didn't like receiving them on my phone at work, because I work closely with customers and my coworkers and would rather them not see such things. After this happened before, I said send whatever you want to me and that it was ok. Today, she left her iPhone sitting on the nightstand and I looked at her messages and they're all cleared from earlier today and prior. I feel like a huge asshole for resorting to this.. Sex recently has been strange as well. She accused me of sleeping with someone else.. which I assured her was not true. She said I had that look in my eye, whatever that means. It's regularly insinuated that I am cheating on her although I have never cheated on anyone in my life. Basically everyone she had been with before me cheated on her.. so she has major trust issues. I work irregular hours and sometimes get stuck at work really late.. or I'll work overnight and end up accused of going out partying. Today she said she wasn't interested in sex and said it's because of the birth control she started last month. We're leaving on a surprise vacation in the morning for a couple days before she starts her new job next week.. I've kept it to myself to not ruin our trip but this is driving me crazy.
<bot>: Wife of about 6 months taking dirty photos, not sending them to me, deleting text messages, lack of interest in sex, etc. How should this be approached? Thanks.
