Marriage is a long-term commitment.
how can the behaviors you practice in a dating relationship enhance the dignity, respect, and responsibility relating to marriage?

It may help if you and your partner still hold that trust and bond you had created with one another and as married you tend to trust each other more and be more open witch in my opinion a female likes more if the male is honest. If they both respect one another and take care of each others responsibilities then there will be no problems

(Hopefully this helped)

Your behavior show who you are. And that's one way people judge you. If you show respect, people will (or at least should) respect you back.

Here's some tips on how to create mutual respect and ongoing love:

Take time off to spend time with one another. Respect each other, listen to each others concerns, wants, dreams, ideas, ambitions, and everything in between. Make sure that you make it clear that you are there for your partner when they need you most. Take responsibility. Every now and then surprise them with something they love. Keep the romance alive. Make an effort to compliment them. Even if its just on the little things. People like to be appreciated. And never forget, don't hide your any of the above from them. Tell your partner your hopes, what you want, how you fell. Make sure to communicate! SOOO many marriages end in divorce because they forget to do the above. Good luck!
