Stop pursuing her because you will only push her away even further. Women never respect men who chase them.
If I were you I would come back to my own things and leave her doing her own.
Also, don't look for too many explanations. It's obvious that she wants something else and you need to give her that space.
She is bored of you and she is probably looking for a different type of guy, a different personality or she simply wants to know more people.
You should do the same.
