How do you know if an older woman is interested in you?

if you talk to her, she talks nicely to you and different from other men. she feels nervous and not her self around you. Please try not to ignore her because it is a turn off and it hurts. If you really wants a relatiOShip with her, just go up to her and talk nicely and she would love you for it

You can simply ask her. Just because she is nervous does not mean she wants a relationship. If she spends time with you and wants you to be in her life, she may want a relationship.
