If your partner finds out you’ve been tailing him/her in your car, he/she will no longer trust you on dates. Sending others to do your dirty work. Don’t ever send a friend or anyone else to gather information for you about your partner or to spy on your partner for you. This means, don’t send a friend to go hang out where you know or suspect your partner will be. Dates have your friend try to eavesdrop on your partner’s conversations in places he/she goes. Dates ask your friends to use their cell phone to snap covert videos of your partner. All of these favors from friends not only violate your partner’s trust, but also reveal your total lack of trust in your partner. Checking up constantly. One of the biggest ways to reveal that you don’t trust your partner is to manifest that distrust with paranoid and obsessive behavior. While calling your partner regularly is quite normal, calling him/her incessantly to check up comes off as obsessive and will drive your partner away. If, for example, your partner is unable to answer his/her phone for a few hours and by the time he/she accesses it he/she discovers you’ve called 50 times, you not only come off as being paranoid and obsessive, but you clearly communicate to your partner that you distrust him/her. Also, when you panic every time 10 minutes go by without a reply from your partner by a phone call or an email dates, it sends the exact same message. So even if you have some type of intuition that your partner is hiding something from you, it’s better to engage in a confrontation with him/her openly rather than searching for answers secretly.
