unknown message

this early morning I receive this message :

"percaya sama satu hal,semua orang punya orang yg disayang.dan wajar kalo orang itu pertahanin orang yg disayangin nya waktu dia pergi :)
maaf yaa."

Well, I don't know who sent me those words, I even don't have his/her number on my phone. I just confused what the sender mean by sending me those words, and it just makes me feel more doubtfully now
