Stop contacting her by not calling her or text messaging her for one day. If she text messages or calls you, it might mean that she wants to spend time with you and can't go a day without talking to you.
Suggest to meet up with her spontaneously. If she drops everything she's doing with a smile on her face and will willingly meet up with you on a whim, it means that she enjoys spending time with you. This might mean that she is falling for you.
Look at her facial expressions. Check to see if she has a smile on her face around you, even if the two of you are not talking. This may indicate that she enjoys being in your presence, no matter if you are on a fancy date or are sitting at home watching a movie.
Ask her about her future. If she talks about the future positively and you are included in it, she might be falling for you. If she does not include you in her future or is annoyed by your question, this might be a red flag.
Go along with her when she wants you to meet her family. This big step means that she thinks you are important enough to introduce to people who are important to her.
Watch to see how caring she might have become. If she sets up small surprises for you, celebrates the positive things in your life and becomes sad about your problems, she might be more into you than you think.
Hang out with your friends and her to see how they get along. If she fits right in and has fun with your friends, this is a good sign. Switch it around and hang out with her friends and her. You want to make sure that she talks to you as well as her friends when everyone hangs out.
Give her a small gift and look at her reaction when she opens it. Watch to see if she seems truly grateful and appreciative about the small gift. If she does not thank you for the gift or does not seem interested, this might be a red flag. If she gives you a gift without any special occasion, it might mean that she cares and thinks about you.
Ask her, face-to-face how she feels about you. If she is comfortable around you, she should be able to tell you how she feels about you, whether good or bad.
