I've been with my now wife for 17 years. Most important rule:

Make dedicated time for her every day for a minutes, every week for a few hours, every month for a few days, every year for a few weeks.

That basically means dedicated listening for one short conversation a day, one dedicated dinner each week, one dedicated weekend together each month, and one dedicated vacation together each year.

Any by dedicated, I mean no phones or computers or texts. Give her your time. It need not be huge amounts. But show she is important.

Of course you will fall short. But the goal is to try. She will see that.
