When does a woman know man is in love with her?

Well look into her eyes and see if they are glowing when she looks at you. In fact is her whole being glowing when she's around you? People show there love in many different ways. Does she call you to let you know she was thinking about you? Does she give you little tokens often? Does she like to cook for you? Does she seem to dress a little different for you than for other occasions? Has she told you that she's fond of you? Can you see a difference in her affections since you began the relationship? Why not just ask the lady, if you felt the need to? then there is probably something to it. The other question is do you feel the same? If so, dont leave her hanging.
