For any young person it's important to know you can support yourself both financially and and socially. IMO it's important to live alone and not only get to know yourself but build that strength of knowing your own capabilities.
If you've already committed to being child-free in your head and heart--that's okay-- but your partner needs to know long before the wedding or it's not fair to anyone. You need to be on the same page as your partner when it comes to these huge life decisions. Be real. Be mature. Share your truth.
Who knows if, and/or when, anything will return to what we once embraced as common-place. For now you may have to dig deep within yourself to find small things for which to be thankful--but it's there. Whether it's the fact you're able to get out of bed, you have food to eat, or you're able to put on your socks...find the gratitude. It will make a difference.
