What if I really miss my ex but he doesn't like me back ?

I think you will know all answer by spy app like 1TopSpy, It works by tracking and monitoring all activity in the background of his phone including: track GPS location, spy on text messages, web history, images, calls logs and spy call recording, spy on Whatsapp, Viber, Facebook messages, Snapchat, Line, BBM messages and much more. Then you have an answer if he still love you
