He got home from work last month. He works a normal 9-5. He got home per usual and we laid down in bed because he and I usually relax once he gets home. I work usually nights I bartend but was off this evening. While we were lying down I noticed a sweet perfume smell on his shirt and neck. It was very much in that one spot of his collar of his t shirt. Once I asked him about it he said it could’ve been the laundry detergent concentrated in one spot on his shirt. I let it go because he said he doesn’t know what I was smelling or how it could’ve gotten there. I just find it weird it was in one spot and on his neck as well ? It was 100% perfume and only on that part of his shirt. I don’t he is cheating truly. Any ideas where it could’ve came from.
