Feelings follow actions. If you want a return of the feeling of extreme like you had when you first met you must do the actions you would have done then. Treat your wife like a queen! Treat your husband with respect. Tell them how much you love and appreciate them and do things to make their lives easier.
True love comes in response to a decision to take action. So go out there and act like you have just ‘fallen in love’ and soon you’ll discover that it’s as beautiful as you remember.
