We've been engaged for over two years and have no immediate plans to get married, lol. Weddings are really stressful and expensive... So we're putting it off until it feels right (which might even be never... both of us don't feel as if we need the paper and title to validate our relationship... but I like the idea of getting all my friends and family together to celebrate our love).
This whole venture into poly has put a bit of a stop on it too. We've both been kind of changing/challenging all our past beliefs.
