Create routine and structure around making time to talk.
Perhaps you take 15 minutes every evening to go over the day and talk about the next one. Deeper issues can be tackled as well as determining who is picking up the kids from school. Identify how you will work to create the routine together and find ways to keep each other accountable. If you have conflicts, reschedule the time, but avoid skipping it. That too becomes a habit.
Some ideas:
Give the time a visual cue. Put a note on the fridge, a cheesy decal that makes you smile on the bathroom mirror or if tech is your thing, make it an event in your calendar so it shows up on your phone or computer.
Tell your children and other family members that the time is set aside for you and unless there is something critical, it will remain sacred.
Find a place in your home that is comfortable to sit and see each other undisturbed, even if you ban the other household members from the kitchen and you set up two camp chairs.
Bring a beverage or dessert to the conversation and make that part of your ritual.
Take an evening walk together.
