Smiling, flirting, compliments,- is there any way to tell when they are simply friendly and when someone is interested in getting to know you more intimately?

Maybe That’s too funny a way to say it. Basically, how do you tell (if you even can) when a woman is friendly to be friendly Vs. she has romantic interest in you? I’ve lived under the impression members of the fairer sex never thought much of me in such terms.

Also sorry if anyone is tiring of my relationship questions
