Since we have been married over 46 years, I thought I would jot down several ideas which might be applied in your relationship or marriage. 

• Should one of you enjoy cooking, gather in the kitchen and cook some homemade delicacies together.  Create a romantic dinner with candles, fine china settings and flowers.  Sometimes just cooking together is rewarding without the romantic dinner setting. 
• Quality time.  Haven’t we all heard that phrase.  It is real.  Spending quality time together will make your relationship stronger.  So take some time out of your busy schedule to be with each other.
• Being honest in your relationship is important.
• Being honest in your work and never neglecting your profession can be rewarding for both of you as long as you do not forget each other.  Becoming caught up in your work and neglecting your mate is one of the greatest downfalls in a marriage.
• Both of your dreams are important.  By understanding your partner’s innermost desires, whether it is personal or professional and lending a hand in your partner realizing them, will have great rewards.
• Without mutual respect, love can not sustain.  RESPECT each other.
• Two way communication is required for any relationship to grow.  Being married makes this two way communicatin mandatory.   If you don’t communicate with each other, how can you get a clear understanding of your partner’s physical and emotional yearnings?  Believe me, love flies out the window if couples do not communicate on an intimate level.  My husband and I found this out and spent 6 years bridging the rift that grew between us.
• When an argument begins and you do not want to argue, walk away.  However, do not stay away, emotionally or physically.  Remember your spouse is upset and you both need to communicate with each other.  After the temper has cooled down, take a walk, hold hands and remember some special things you admire about each other.  When or during the walk, talk out the “thing” that was bothering your spouse.  You might be surprised what truly set your spouse off wasn’t something you said or did, it might be an accumulation of “things” that others had contributed to their day and your statement or action brought it all to a head. 
• DON’T go to bed angry.  Anger builds and destroys relationships.
• Lend a patient ear to your partner even if you do not feel like it. 
• Give each other a hug and kiss throughout your evening.  These little surprises do mean a lot.  However, realize when your partner is busy with an important project.   Saying you love them, bringing them a cup of coffee or tea, touching their shoulder in passing, etc. will remind your partner that he/she is loved and you miss spending a few moments (or hours) with them.  That partner should remind himself(herself) that their partner is telling them something special.
• Respond in love.
