I can see both sides of the argument when it comes to this situation. On one hand, using a monitoring tool is a direct way to get the information you’re looking for. Apps designed for this can give you access to messages, call logs, and location data, which can provide a clear yes or no answer. This approach can offer certainty when you feel you have no other options.
On the other hand, you could start by observing behavioral changes. Things like the phone suddenly having a new password, being angled away from you, or a sudden increase in late-night texting can be indicators. This method doesn’t require any technical setup. Ultimately, it’s about weighing the need for definitive, technological proof against observing the patterns in your partner’s behavior. Both paths have their own complexities.
