Question: What are the best things parents can do to stay together and have a happy marriage?

Don't get married until you have the same idea of what you want ... Children? Jobs? Location?
Work on their problems and try to get along better. Spend more time with their children and each other.
Be rational and don't have kids, sex or get married until they are sure they are ready to work through the troubles of marriage.
Sex.
Love each other. Respect each other.
Spend time together as a couple. Work hard to respect and be polite to teach other, and serve each other. Go to church together, and develop a relationship with Christ together.
Compromise.
Be absolutely honest with each other.
Do kind gestures, say nice things and love one another.
Read the Bible and pray.
Be open and honest. If you're upset then just be adult and say so and why. If your partner is upset then listen and try to make the situation better and not just lay blame.
Talk over their problems and compromise.
Money.
Don't fight.
Wait on God.
Spend time together alone. If they're around children all the time they're so focused on the kids, that they forget about each other, and they have a hard time living in the same house and working around each other. Also having a good overall family relationship helps the marriage stay together.
Look over each other's faults and think about your children. It's hard to grow up with only one parent.
a) both be Christian. b) have kids (also Christian). c) spend time with their family.
Try to rekindle the flame.
Pray, and if problems occur see a therapist.
Talk about everything. Get to know each other before you make the commitment of marriage. Have kids and play with their kids. Have a religion that promotes good family relationships.
I don't know because I'm not a parent, but I think probably listening to each other and compromising with things.
Talk out all problems. Stay faithful, or admit that they find it difficult to remain faithful. Take regular holidays and have time together, so the only time isn't after work, because stress after a bad day can break people.
Lead a God-Centered life.
To have a relationship with Christ and to live a Christian life-style.
Talk things through, listen, have open conversations.
Not be selfish and think about their kids.
Family time :) If problems are starting up, try marriage counseling or talking. It can be very simple to solve.
Love each other.
Think about their children. They should also go over rules beforehand so they have the same idea.
Have a designated "date night".
Build a strong relationship in God before and during their marriage.
Communicate.
Talk to each other.
Just live a happy life.
Why are you asking me?
Go to church, have a family talk once a week, and just tell each other about their day.
Learn to accept the other how they are and being as loving and caring as possible.
Live their own lives, not separately but still have independent things to do as well as doing things as a couple. To understand and agree with each other.
Love God and each other.
Agree to disagree, work out the problems together without yelling.
Get to know each other before the wedding. Figure out who is going to handle the money, and what you are going to do with the family money. Don't have kids, TV or pets until after the first year of marriage. It distracts you from each other.
Have sex!!! I'm pretty sure that's what my parents do ...
Love Jesus.
Make sure that they want to get married in the first place.
Spend alone time together and listen to one another.
Work things out, be honest, talk.
Pray, go to counseling.
Love each other.
Spend time alone when necessary, and compromise. Also, be open-minded and well-adjusted for change.
Respect each other.
The best thing for parents to do so they have to stay together and have a happy marriage is being in a relationship before marriage for a couple of years.
Give them gifts.
Listen to each other and respect each other. Do not cheat, even if it is someone hot or whatever. It doesn't matter. Do not hurt one another because abuse can lead to your children doing the same thing. You need to set a good example for your children.
Spend time as a family.
Have a decent relationship with themselves and God. Discipline also.
Dont rush into marriage.
Show each other love. Try not to argue. Agree with each other.
Talk to each other! Lack of communication is a big issue!
Spend quality time together, choose their battles wisely, compromise, equals.
Tey can enjoy their life and make sure that the line of trust isn' broken and everything is good and happy, no awkward atmospheres and can talk to their other partner about anything and be honest!
Think what's best for the child.
Be intimate and care about each other and keep your legs closed to other people.
They should communicate and work things out.
Stay on each other's sides.
Jesus.
Be open and honest with each other and not let trivial things such as money get in the way of their marriage.
Find time for each other each day. Make sure all issues are discussed before rushing into marriage.
Keeping the "spark" alive by going on dates often.
Try. If their marriage gets rough, stick it out and try.
Communicate! If they don't talk, and that includes having time that's just for them, then the marriage may not work out, but if they communicate and are on the same page, things should work out.
Trust, honesty, love, commitment.
Think about the sake of the child, how would they grow up thinking marriage is bad.
Plan family nights, vacations, eat dinner together, go out.
Take time off from each other once in a while.
Both of them have to work at it.
Be nice.
Know each other longer before marrying.
Practice healthy lifestyles and do the best they can to work things out.
Get married when they are well acquainted with each other.
Stay faithful to one another, communicate well about things and spend quality time together. Most importantly, to not rush into getting married in the first place.
Increase their knowledge for each other.
Well, I believe if you want to have a strong happy family, you need to be able to spend time with your children. Most parents these days are just so busy with work they hardly get to spend time with their children. They also hardly get to spend time with each other. You need to make time for what's most important in your life, and that should certainly be your family.
COMMUNICATE. And keep in mind that their children can generally hear their fights.
Talk.
Work things out.
Understanding and communication between each other.
Keep their tempers in check, don't play the blame game, and be considerate of one another.
Probably hang out more or go on dates more. Or for some, have sex.
Agree to disagree.
Counseling, keeping their hands to only each other, communication, love.
Open communication, Counseling.
