My exgirlfriend is taking hot nudes to send to some dude she's flirting with online

My foxy girlfriend has been acting weird lately and I decided to gather some evidence if she's cheating on me. I filmed her ealier in the day taking sultry naked pictures on the dressing mirror I bet she'll send to the dude banging her on the side. I think I should just let her go, because I'm clearly not enough for her.
