Does it actually matter whether you flirt with someone or not in order for them to (potentially) develop feelings for you? A lot of people have told me it’s intrinsic, as in “If they like you, they like you.” So you should just treat the person you’re interested in like you would any other person.
So if it all comes down to connection and looks, doesn’t that make flirting a bit redundant?
Edit: To clarify, I see flirting as banter to make sexual/romantic intentions known.
Seems like this was answered already, but I’ll add my two cents. Attraction isn’t always 100% physical. It can be and often is tied to personality. Flirting is a way to show your personality in a more intimate way. A good flirt can cause someone else to develop attraction where without it that attraction may not have developed.
