Story that ends with "now i know that no man can be trusted" 450 words

Here’s my Ex: it was the day of our 15yr anniversary, my husband just stared at me in confusion while we ate breakfast. He knew I was expecting something from him. He gave me a kiss before he left for work and said he’ll be coming home late. I just sat there at the table stunned and shocked. He couldn’t have forgotten about today right? No he wouldn’t do that. I went to make him something to eat for lunch which I usually do every year. I hoped this would spark something in his brain and I mean this is the most I could do my husband. I made him favorite Smoked Gouda and Apple Butter Sandwich. I drove to his workplace i informed the desk clerk who I was. I walked straight to his office and opened the door..I couldn’t believe it !! He was all over his secretary I stared at him for what felt like hours but only minutes. He tried to explain that it was a misunderstanding but I knew what I saw and what was happening.. now I know that no man can be trusted.
