If you confront your partner about suspicious behavior and they don’t take you seriously you should be very concerned. It’s common for a cheater to make you question your own intuition. Chances are if you are feeling suspicious, it’s not without reason. Don’t allow them to make you feel guilty for raising concerns. Don’t let them use reverse psychology to accuse you of adultery. Be aware of attempts to threaten to leave you if you question them. A faithful spouse will be hurt that you think they are cheating but will also be willing to address what behaviors they have that may lead to your insecurities. If you find that your spouse would rather discredit your concerns than address them, it’s a very strong sign that they are cheating on you.
