My (29M) wife (28F) said she's always afraid of saying the "wrong" thing. I don't know what's going on and she won't help me figure it out.

I had a conversation with my wife where she admitted to fearing she'll say the "wrong" thing.<br><br>I have a wonderful wife. I'm generally satisfied with my life. My marriage has been excellent, and we're absolutely happy together. I genuinely love my wife.<br><br>Last night, while I was preparing dinner, my wife said she didn't want to be "quiet" anymore. I was surprised and asked what she meant. She replied that there were many things she wanted to say but felt she couldn't. She wanted to express herself more freely without saying "the wrong thing".<br><br>I tried to clarify what she meant by "the wrong thing," but she didn't want to elaborate. I reassured her that she could say anything without fear of judgment or conflict, but she insisted that she was fine.<br><br>I let it go, thinking she just wanted to express her feelings. I thought she might have felt uncomfortable speaking her mind because I'm a naturally direct communicator. I apologized for any unintentionally hurtful comments I may have made.<br><br>This morning, however, it still bothered me. I don't want her to feel afraid of speaking her mind, yet I'm unsure how to approach this situation.<br><br>What could "the wrong thing" be? What can I do to help my wife feel free to express herself?<br><br>Please provide your thoughts, as I feel stuck in this situation.<br><br>&#x200B;<br><br>TL;DR My wife admitted to fearing saying "the wrong" thing, but won't elaborate. I want to help her feel free to express herself, but don't know how.
