I am very happily married and we have a 12-days old cute little daughter. Just like any normal family, we sometimes get upset with each other but we immediately talk and if we don't want to talk about it right away, before we go to bed, we talk about the issue/difference and solve the problem. I don't remember a day when we went to sleep without our hearts clear of any anger/misconception and I believe that is the key to a successful healthy relationship.
Those relationships fail fairly fast where the spouses don't discuss their problems/differences with each other and let the distances come between them by shutting down the communication channels.
I loved when i read this, really a good tip. I will remember this too. thanks shikra!
