The initial excitement of marriage is always very high. After a few years, though, you will begin to take your relationship for granted. The sparks will start to wear out, and excitement will turn in to comfort.
After you have become used to being with each other all the time, the relationship takes a back seat, and you get busy with home, work and the children. Your life becomes more routine and everything around it becomes a chore, including the sex with your partner. This is when it is common for couples to start to drift apart.
This is normal for your relationship. All you need to do is identify it, and begin to deal with it before you have gone too far apart. It is very important to discuss your problems and your day with your spouse. It helps in bringing both of you together. It is not good to be overly dependent on any one partner. Each one needs their own independence and space, and it is good if you could try and solve some problems on your own as well.
If you are arguing with your parner, it could sometimes be that you are one in the wrong. Sometimes, even after realising it, ou may just try and bring up other topics for arguing about rather than finish dealing with the problem you started with. Admit that you are wrong and be brave about it. It will ensure that you have a better relationship with your spouse.
It is imperative to trust your spouse and not be suspicious about him or her all the time. The more you distrust, the more you drift away. explain to your spouse if you are having any problem regarding them and their colleagues or their friends rather than bottling it inside you, and bringing it up in arguments at the wrong time.
Accept your spouse for what he or she is. He may be sloppy, unpunctual. sometimes they have obsessions for things you do not understand. Empathise with their needs and deal with it by giving them their space and taking them for what they are.
