If this is the first or second time she is replying to your texts late, then it is not a big deal. She might be busy with work or running errands.
However, if she has made it a habit to respond to your messages late and takes hours before texting you back, then it could mean she is no longer interested in you.
Here are some of the reasons why she is responding to your texts late.
1. She is annoyed with you
There are several reasons why a girl can be angry or annoyed with you. It could be that you didn't fulfill your promises, or it could be that she is still mad about the last fight you had.
2. She is no longer interested in you
Once a girl has lost interest in you, then she will show it in many ways like ignoring your texts or taking ages to respond to your messages. It could also mean that she is interested in someone else or she simply wants to be left alone.
3. She is seeing other guys
Ever wondered why she is taking too long to respond to your messages? Well, the reason why she is doing so could be that she's found someone else. This could be her way of telling you she's moved on.
