Love happens. It can blossom between strangers on the street or between friends. It can be difficult to deal with unrequited love as both recipient and lover, especially when both of you are friends. Before attempting to cross the boundary of friends and lovers, pay attention to some of the subtle signs she may be sending you so you don't end up ruining the friendship.
Some woman are very touchy-feely. However, most woman become increasingly touchy-feely when they are attracted to someone. Pay attention to how she touches you and when. Compare how she touches you to how she touches other friends. A tap on the shoulder or nudge to the arm may seem harmless but if she always seems to be brushing against you, she might be interested in more than friendship.
The way she positions her body and maintains her personal space around you is a key indicator of her feelings. If a woman tends to sit with her legs crossed at the knee and facing you, she might be interested. Furthermore, if her pupils dilate during a conversation with you, her eyes might be expressing attraction.
If she is constantly trying to get you alone, whether to hang out or go out just the two of you, it may be a sign she is into you. She may want to spend time with you one-on-one to prove that you two can have a great time alone.
Showing deeper concern for your dating life and romantic interests is a sure-fire sign your female friend wants to be more than friends. If she seems sad and down when you bring around a date or continuously asks for information on your relationship status, she may be interested in you.
