Loyal or not

People say dogs are loyal to their owners. Do people stay loyal to their partners too? If they are committed there is no reason they shouldn't stay loyal with their partners. Fights and small conflicts occur and it makes us stronger when we deal with future miunderstandings. This does not mean that couples should give up easily on their relationship they've built for weeks, months or years, even. Nevertheless, some took for granted in the relationship they've commmitted. Being unloyal is not an excuse when you're somewhere else. If you know you can't get involved in a relationship while you're away from home country, better end it there and then. You know you'll end it someday, why not before you commit yourself here? It is unfair for the person who falls for you, thinking he/she can be with you. There is always misinterpretation in body language among people. Perhaps that's why it is difficult to know what a person is thinking while the gesture he/she puts up is not synchronise with its thought. Anyway, this topic is my personal view. What do you think? What does loyal mean to you? :)
