[header] How to spy on text messages [title] Please consider an alternative to spying. [step] Never throw around false accusations and never judge your current lover by what people in your past did to you. Only resort to monitoring someone's device usage if these tips fail and your suspicions are not simply based on jealousy, but reasonable suspicion. 
It is always better to be upfront and simply ask to see your significant other's phone. Same thing applies when wondering who your child is texting.
