Damn, used condom is Cpt Obvious kind of discovery, this guy probably was self-mad for leaving such evident proof, which was so easy to hide. But, this story also reminded me of mine, little trickier :D I found out my ex was cheating on me because I found....a hair. Single, thick, curly, dark brown hair on my dark brown kitchen table, which for the life of me, couldn't fall of my head, as I have straight blonde hairs. I decided to investigate together with my only female friend who visited us some time before my discovery and btw, she had similar hair. So I hoped it's just hers because there is no chance in the world she would do that to me (fuck my guy). So, I took the hair I found (in a tiny string bag) to her place, she took one of her hair, we compared them both on a white sheet of paper. Nope, it wasn't hers - not so thick and curly and had different shade of brown. So I went back home and confronted him about which bitch is loosing hair in my own house where I'm working night shifts and if she's cleaning his dick, why can't she clean the kitchen too because I love my sandwich with tometoe, not with hairy hoe . Turns out it was his coworker Rose, I demanded to stop the romance immediately and stayed with him for another FOUR years of dead bedroom (during which, he had a second romance with another coworker and I found out by reading single text from her) until I finally broke up with him over this very reason. I was young and stupid, should have been dump the guy right after my first discovery, but I loved him very much and hoped to fix it. Before that events I thought "finding hairs" is possible only in cliche cinema movies. Now I know those movies are inspired with cliche life, no shitting.
