So I have known since the moment I met my fiancée that she was the one for me. She is perfect in every way and is so good for me. There is not a thing that I would not do for her. I help plan the wedding and help with anything when it comes to it. Recently, we have been looking at houses and planning the wedding and she gets overwhelmed. She told me that she no longer thinks that she can get married. She said she doesn't know why either. She said we get along good, we have the same goals and dreams and we love doing the same things. She even told me that I would make a great husband. She just kept telling me that she is having doubts about the marriage, and is waiting for some moment of assurance to know that she wants to get married. Now she is being distant and not acting the same. She still plans to buy a home with me and we are still looking at houses. But she rarely mentions the wedding. I need help on what to do. Is this normal?
