When your spouse shares about something that is making them feel down, your role as their spouse is to make them feel supported and not alone.
Let them know you appreciate their sharing with you and acknowledge that it might have been difficult to do so. When you do this, it signals that you are a safe place for their vulnerability. “I’m glad you told me. What can I do to help?”
“Thank you for trusting me with this. That really means a lot.”
“This must be hard to talk about. Thanks for opening up to me.” In this way you are showing that in the moments when they are experiencing their worst, you are strong enough to go through it with them. No matter how bad it gets you will always be there. It will give them a sense of security knowing that they can be completely vulnerable.
