It's easy to ignore red flags in a potential partner when you're infatuated or in love or hellbent on getting married. People in relationships often pretend not to see the warning signs, or tell themselves lies like: "maybe they'll grow out of it!" or "I can change them!" or "once we move in together, they'll probably be more than happy to give away their collection of taxidermed moles!"
But in most cases, people don't usually change that much, no matter how hard their partners try. And the mole collection is likely to grow in size until it has its own wing of the house. Red flags are warning signs, and you can choose to listen to and address the issue before a relationship becomes a marriage. Or, you can close your eyes and hope they'll go away (but just FYI, they probably won't).
