The phrase "how do you know if" is too broad and incomplete on its own, but common uses include questions like "How do you know if you love someone?" or "How do you know if you're in love?" Based on the top relevant source from Healthline, signs you know you are in love or deeply care for someone include:
- Your thoughts return to them regularly.
- You feel emotionally safe with them.
- Life feels more exciting because of them.
- You want to spend a lot of time together.
- You feel a little jealous but also compassionate toward them.
The experience can vary for each person, including differences between romantic and platonic love, but these emotional, mental, and physical signs often indicate love or deep affection. If the user meant something specific by "how do you know if," such as how to know if a feeling is genuine or how to know if someone likes you, those can be addressed with more specific queries.
Please clarify if the question is about a particular context (love, friendship, trust, etc.), or I can offer a general explanation of how people recognize certain states or truths.
