Being in a relationship with someone who for whatever reason can not be with you for an extended period of time can be very complicated, especially if that person is a spouse. Now I am not talking about a week or two weeks or months, but years. As human beings we need companionship, emotional support, and physical contact. Although you might have an emotional connection to your partner if you are separated for an extended period of time you will only be able to go for so long before one or all of your needs, needs to be met by the other.
No matter how faithful you try or want to be you will at least try to find a way to combat your loneliness, and you will seek companionship and emotional support somewhere, and depending on how long the separations from your partner is going to be your physical needs might come into play as well, therefore I advice you both to be very watchful of your sexual desires, when you are apart for a long period of time.
In a perfect world we would be able to sustain and be at our most faithful and loyal when we are away from the one we love for extended periods of time, but that’s not always possible. It is really important that you both be honest with yourselves about what you need emotionally and physically, and the needs you can and are willing to suppress, but whether it is your emotional or emotional and physical needs that you need met you are going to find someone to fulfill your needs because it is emotionally and physically impossible not to, because everyone needs some form of a connection, and everyone needs some form of intimacy, especially in a relationship, and more importantly with a spouse. We all at some point in our lives desire to feel loved and completely satisfied sexually, physically, and emotionally, and we desire to be faithful to that partner.
We all want to believe that someone loves us so much that they will be faithful and want no one else but us, but even if you or your spouse just find companionship through someone at dinner, or in general conversation once a week you are finding someone to fulfill a need in your life. Some couples never speak on what goes on when they are not together although hiding things from each other is not wise, and some couples are very open about what goes on when they are apart. You and your partner have to figure out what you want or need to know about each other, and you definitely want to communicate your feels about the relationships each of you have, other than each other.
The thing is you have to be realistic we all have needs, wants and desires and a person can only go so long before those needs, need to be met by you or someone else. Do you know if you can be faithful for an extended period of time?
