Snoop on their phone

Does your partner carry their cell phone with them wherever they go, even if it’s a trip to the loo? If that’s happening in your relationship, there’s a good chance your partner’s up to something. Take a peek into their cell phone when you get the chance, especially when they’ve put the phone on charge.

Erased phone logs, a password protected phone, several calls to the same unknown numbers, or phone bills without detailed call information are all good signs that your partner is trying to hide something.
