You love your wife, and she's hurting. When she's had a bad day at work, or a fight in her family, or is sick, or anything else challenging happens, what do you do?
You're there for her, right? Do you listen to her, show her empathy, hold her? Do the same here. And when these triggers come, apologize to her for causing her so much pain. Don't be afraid to apologize and to listen. Show her you're there for her "in sickness and in health". If that's where your heart is, don't be afraid to do it. Especially do a lot of listening. It's one of the best ways to show you're THERE with her.
Wish you both healing.
