If you happen to find an unusual text message or phone number on your boyfriend or girlfriend's phone, the first step is to remove yourself from the situation. Take a deep breath and think through what you've read before making assumptions.
Next, talk to your loved one as soon as possible about your suspicions. Keep in mind that you'll need to have a good reason why you were going through his or her phone, which will be seen as an invasion of privacy.
Depending on the reasons you receive from your loved one, you may want to consider speaking to a psychic. If you feel like he or she may be lying to you, seek a tarot reading sooner rather than later. This can help you better perceive the future of your relationship and move on if necessary.
