It has been long since you walked down the aisle, hasn't it? Or even if it's not, then there is something that is bugging your marital relationship.
Marriage is a relationship that demands love and care more than anything else.
If you married the girl/boy you loved (arrange marriages are history now I suppose) then obviously she/he would be requiring the same amount of love and care which you used to give her/him before.
There are times when your partner cannot understand the other responsibilities you have and from here the problem arises.
To fix a marriage back to the times which you loved one another is a big job to be done.
The most important thing in doing so is to make sure that your partner is interested in it as well.
Both of you should take out time from your busy lives, go out to a park and talk.
Unless couples discuss their problems, demands, and their needs, no one can help them to fix their marriage.
Sometimes only minor differences lead to big conflicts.
So, try to respect those differences, and if you can't, then talk to your partner about ways how to deal with it.
You need a lot of patience to fix a marriage.
One cannot mend what has been left damaged for years.
The very first step to help your marriage come out of the dangling phase is to honor each other's differences and reduce your expectations.
When you are married, you are no more a teenager who has to hangout with a girlfriend.
