Marriage changes the relationship. Not just a little but dramatically. Not always for the bad but most times for the good, the changes could cause problems though. Although the largest part of getting married is because of love there is also trust and comfort. Once a couple get married their whole world goes upside down because maybe they were to comfortable.
To avoid the scary and unnerving changes communication and honesty are key. If the intimate part of the relationship and marriage is fading then say something about it. Suggest trying something new and different. Or get suggestions online. The romantic side of things may just be buying flowers or acting like it’s the first date all over again. There are many simple solutions to many of these problems.
In any case if there is the feeling of boredom and it isn’t addressed then there could lead the possibility of disloyalty, which then turns to distrust. Of course in a marriage that isn’t what any couple wants. I know that there are couples that watch adult rated movies together, or read the pornographic magazines together, and that is not to show them that their intimate life is dull, but to find ideas that lay behind the story that is read or the scene that has been watched.
There are a couple of web sites that hold ideas and thoughts, not only in the intimate aspect but also the romantic, guiding those that need some extra insight along the way. Not every person is perfect, nor can minds be read. If something is wrong or isn’t happening in the couple the couple needs to communicate it. Most marriages that last forever happen to be because they always work on communication. Communication is never perfect either and as long as couples remember to always keep lines of communication open then the longer and happier the marriage will be.
