Hi. I’ve broken up with my ex bf and was getting rid of some of his stuff and found these marks on an old t shirt of his. He would never go out in this t shirt and just uses it for painting around the house etc but I’ve found what looks like a lipstick mark on his sleeve???!! The mark is on the sleeve in a straight line and is nowhere else. There’s gaps between the marks so I can’t tell if it does look like a lipstick mark or not… obviously he’s an ex but would be nice to know if he had been cheating all this time!
