Unfortunately, this has happened to me before
My ex husband called me up and told me his Dad was sick and he was taking meds over for him and he'd be home late because he was going to hang out with him, I didn't think anything of it.
I decided to make my Father in law some soup and take it to him because I felt bad for him feeling so sick.
When I get to my father in law's house, his car isn't there but my husbands is. I knock on the front door nobody answered, so I went around the house to knock on the bedroom window (figuring he was watching tv and couldn't hear me over the noise).
I heard them through the window. I started FREAKING OUT and acting like a legit lunatic. I absolutely hate confrontation but this was like I wasn't even myself and I was just so shocked. I cussed, I yelled, I had a full tantrum. He came outside, starts crying immediately "It was a stupid mistake" "We just work together and one thing led to another" "Please please don't leave me." I didn't want to hear anything. I just kept ranting and raving.

It was like being possessed, I was so angry, I'd never been that angry before and haven't been that angry since. Cheaters are the worst.
