Relationship Renegotiation

We moved and now live together. After half a year, I have the impression that the emotions have died down a bit and the move itself may have caused us some stress. I know that my partner wondered if the move was necessary, and she may have thought about it a lot. She wondered about her decisions, whether she should have thought about it earlier, and if she could withdraw. However, she probably doesn't want to anymore. I don't know if these emotions introduced a bit of seriousness into our relationship for a moment. Maybe this is our first common challenge, which I hope we will survive. I am able to tell her that I love her and look at her with happiness. On my part, I realize that curiosity about her opinions, words, feelings, and differences must certainly be built, and that openness about this can allow us to get even closer. I have a lot of fears, but I try not to take my thoughts for granted, because they would like me to give up easily. Together, we deserve faith in ourselves and in our ability to create a beautiful relationship together. What steps can we take to navigate this situation and strengthen our relationship?
