Was My Ex Spying on Me?

I've had a feeling for awhile that my ec has been spying on me. He even told me that he has ways of keeping an eye on me. Found out he has pictures of my partner coming into the house.

Last night, on the phone, I had mentioned the thought and right after we had to recall each other at least seven times. My phone had a battery loss and significant amount of data output. Plus my phone had been restarting randomly. Things added up and I did a factory reset.

Since then, battery life has been good and no more random restarts.

Pretty certain there was spyware on my phone
