Been there, ex bugged my phone, computer and house.

He didnt have to be in same room or near my phone, he called a seperate device and simply listened in. How he got my texts I dont know but he did.

I wish I had gone to the police now, I strongly advise you to go to the police from experience.

Do you know what kind of software and how did it get on your phone? Do you know what to look for to see if someone has something on your phone? Please let me know?

I agree POLICE, POLICE, POLICE. That is stalking. How creepy. Take care.
