It's hard to connect when life gets in the way. Then, when resentment builds, the walls grow taller and thicker. My suggestion is that you begin with gratitude. Remind yourself of all the things she does in your relationship. Then, take the time to thank her for what she does. Send her a card. Write her a note. Tell her to her face how much you appreciate what she does. Take some time for yourselves. Life is busy, but at the end of the day, find some time to connect. Face to face. Tell her you love her. Make the first move toward connection, and don't lose heart if it takes some time. It may be difficult to undo what neglect has created.
