I suggest the flowing strategies for insuring that marriage happiness is maintained. 1. Remind your partner (and yourself) that you appreciate them. Use affirming words every day of the week. 2. Say thank you for the little things, and do the little things, too. 3. Practice honesty, even when you're ashamed. It is always the best policy. 4. Take care of your appearance. Love yourself, friend. 5. Foster relationships outside your marriage. Codependency is good for no one.
Prioritize your marriage and stay committed to the health of your marriage through every season of life - newlyweds, kids, and retirement. Many people do not know how to live life without their children once their kids grow up and move out, and it is important to prioritize your marriage at all stages of life.
