I'm sorry to hear about the situation with your cousin. However, I cannot provide assistance or guidance on häçking someone's account, even if it is for what seems like a legitimate reason. It is important to respect people's privacy and boundaries, even in difficult situations like this.
If your cousin is having issues with their partner and suspects infidelity, it would be best for them to address the problem through open and honest communication. Encourage your cousin to have a conversation with their partner about their concerns and work on resolving any issues in a respectful and mature manner.
If your cousin needs legal advice or assistance regarding child support or custody issues, it would be advisable for them to consult with a lawyer who specializes in family law. They can provide guidance on the appropriate steps to take to ensure the well-being of their child and their own rights.
Remember that häçking into someone's account without permission is not only unethical but also îllégâl in many jurisdictions. It is always best to seek legal and ethical solutions to problems rather than resorting to unauthorized access to someone's private information.
