People often fall in love with an image they've created themselves, and during real communication, bitter disappointment sets in. To avoid this, it's important to learn how to uncover your match's life priorities even at the texting stage. And we're not talking about favorite movies or music, but deeper things.
Try discussing the idea of an ideal weekend. A person who loves a quiet rest at home with a book is unlikely to form a harmonious couple with someone who spends every weekend in loud clubs or extreme hikes. You can also gently touch upon topics regarding attitudes towards finances, career, or the division of household chores.
Listen not only to what the person says, but also to how they say it. Do they respect your opinion if you disagree? Do they try to invalidate your experience? The answers to these questions will help you understand if it's worth taking this connection offline.
