Please choose the correct ending to complete the given sentence: Youth: [header] How to know if a guy is cheating on you [title] Look for obvious evidence of another woman. [step] It may seem like a cliché, but finding a smear of lip gloss in a shade you don't wear on his shirt is a good sign that he's cheating. Smelling another woman's perfume on his hair or clothing is another warning sign.

Ending1: [substeps] Remember: this is also a sign that he's trying to get your attention, and so is someone else he may be trying to trick you into thinking is his. [title] Look for an excuse to have your saliva near his mouth. Ending2: Even if he seemed to completely change, the smell of someone else's perfume might have been one of his other designations. [substeps] When two women are in a bar, for example, it usually seems like the woman is the one monitoring his bodily hygiene. Ending3: [substeps] If you notice a lipstick stain or strange perfume on your boyfriend once, it may just be from a friend or relative, so you shouldn't necessarily worry. However, if it happens more than once, you may have cause for concern. Ending4: Be aware that some men overdo it when trying to show that they were just in the wrong spot. If his scent is distinctive, that is okay.
