Despite a number of sweet text messages that you've sent to her, you haven't seen any replies from her and you ask yourself what the problem could be. Read on...
1. She is playing had to get
Sometimes a girl will intentionally fail to respond to you because she is trying to prove 'expensive'. In other words, she is playing hard to get and doesn't want to come across as too easy.
She wants you to make a lot of efforts and they need you to not give up on them. What you need to do is keep on with your texts because she could just be leading you on.
2. She is busy
Another reasons she is not responding to your texts is because she is busy. Remember she could be actually busy but some instances she could be 'busy' as far as priorities are concerned, remember we choose people to be busy for.
Some women switch their phones to silent or vibration mode just so she can't be destructed from their busy schedule.
3. You like expressing your feelings over text
Women don't love it when men express their feelings through text messages. You either call them or meet them up and say whatever you feel for them. This makes up another reason why she doesn't reply to your texts; because she is tired of your text-based feelings.
