You've been home alone all day waiting for your boyfriend to get home from work when suddenly the front door opens. You see him walk through the door looking tired and his hair is all messed up. You walked up to him to ask what was wrong but he dismissed the subject quickly, insisting nothing was wrong. You were about to move on and ask how work was when you noticed faint lipsticks marks on his cheek and neck, which obviously weren't yours. Your heart sunk, should you ask about it?
