What is my girlfriend trying to do here?

So I was chatting with my girlfriend until when she had to go because she had to sleep earlier due to school. So she gone at her time due to sleep for school. Now I opened facebook and scrolling and watching stuff. Until when I found something very suspicious. I found that She posted two links and it pops up as an notification and I got really confused. I even checked her profile and she indeed post 2 links on facebook. I dont know what to do in this situation. Like why did she lie to me about going to sleep. Can someone help in this situation?
