I'm sorry to hear that you're going through a difficult situation. However, it's important to note that tracking someone's phone without their consent is not only unethical but also îllégâl in many places. It's essential to respect other people's privacy and boundaries.
If you suspect that your partner is cheating on you, the best course of action is to have an open and honest conversation with them about your concerns. Communication is key in any relationship, and it's important to address your feelings and doubts directly with your partner.
If you still have doubts and feel like you need more information, consider seeking advice from a professional counselor or therapist to help you navigate through this challenging situation. Remember that it's always better to address relationship issues in a constructive and respectful manner.
