Thinking about your new lover more than your partner is normal and it will likely go away: Infatuation often comes with intense emotions and short-term, obsessive attachment. Remember, you likely felt the same for your primary partner once—it will fade. 

You might feel guilty: If you haven't discussed this with your partner, guilt can creep in. It’s crucial to talk about what happens if someone catches feelings. Falling in love isn’t something you can control—be ready for it.

You might doubt your primary relationship even if it’s going great: This is monogamous conditioning at play. Society teaches us that loving someone else means something’s wrong. It takes time to unlearn that belief.
