Girls who rarely open up to anyone are some of the hardest girls to fall for, but are some of the most loyal people you will meet. Here are ten things you need to know about the girls who never let anyone in:

1. First and foremost, it is nothing personal:

She hides everything, and it is not just from you, it is everyone. Do not feel unimportant if she is not telling you how she feels, it is just hard for her.

2. She is probably extremely self-conscious:

She does not tell you anything because she has probably been shut down so many times. Do not make her feel insecure, because she already has enough of that going on.

3. She wants to show you that she is interested in you, but does not know how to:

She can't open up to you or anyone, which probably means she absolutely sucks at emotions in general. Once again, it's not you, it's her.

4. Give her time to warm up to you (she eventually will):

You may think she is playing games with you, or playing hard to get, but she really does not mean to.

5. She likes you, and she will show it in her own weird ways:

A girl who cannot open up is typically someone who has very little emotions. If she did not like you, she would not feel guilty letting you know by now.

6. If she is ever quiet around you, she is not mad, but thinking:

Girls who cannot open up to others tend to spend so much time in their own heads. She may have quiet periods here and there, but there is nothing to worry about.

7. In fact, 90 percent of the time, she is NOT mad at you:

You are going to think she is mad at you, but most of the time she is just stuck in her thoughts. She will be the Queen of Overthinking, and her silent treatments will most likely not be intentional.

8. She has severe trust issues:

This is a big one. She has been taught through past experiences to trust virtually no one. She is sick of being betrayed and hurt, so do not hide anything from her, honesty is always key.

9. She is a great listener:

She loves to help others because it is her way of helping herself. Talk to her; she will listen to you, and will be so happy to do it.

10. Finally, if she does open up to you, well, you got her:

If she lets you in, you are in. Once she truly opens up to you, you will meet someone that you will never forget. Her pain-in-the-ass qualities will totally be worth it in the end because you two truly have a connection.
