Q4MEN: What are the clues a woman can use to tell if a man only wants sex and not commitment?

Pretty much the title. But PPD rules mean I have to add something meaningful. This is the counterpart to this Q but for women.

This came off a discussion that women give attention and sex up to the wrong men too easily. Instead of the right men - aka those that are kind, decent and want commitment.

So my question is what are the methods that a woman can use to tell that a man is a fuck boy or for real?

EDIT: Please avoid basic answers like “if he’s hot/Chad” then he won’t commit. Or at least add more to it. Like also describe telltale behaviours as well.
