1. Being straightforward and ask how she feels.
It is okay to ask someone about their feelings for you. It may seem embarrassing at first, but if she cares about you, either as a friend or something more, she will get over it and appreciate that you feel comfortable enough to be open and honest. Here are some ways you can ask:
"How do you feel about me?, Do you see me as a friend, or do you see me becoming something more?"
2. Ask love and romantic questions.
If you do not want to come straight out and ask how she feels about you, then ask questions about love that may help you figure things out. Here are some questions for you to ask;
"How do you feel about falling in love?, Do you think people can fall in love after being good friends?"
Then allow her to answer.
3. Ask a mutual friend how she feels.
Girls tell their friends almost everything about their life. If you are too shy to directly ask a girl if she has feelings for you, casually ask a friend she is close to. Be aware that once you start inquiring to friends, they will likely report what you said back to this girl. Here are some simple questions you can ask:
"Do you know if she like anyone?, Does she ever talk about dating?"
4.Find out how much she talks about you in your absence.
If a girl finds a reason to constantly bring up your name, speaks positively about you when you are not around, or smiles when your name is mentioned, she has strong feelings for you, very strong one.
5.Take her out on a date.
Have some courage and ask the girl to go and see a movie with you, or for a dinner. If she dresses up, or puts on more makeup than before, then she is trying to make you happy.
