This state of love can be short lived or last a life time. Some people fall in love young and part only with death at old age. Often peace lasts for a long time as the lovers marry, beget children, children grow up and leave home. At this point many families have a crisis. Some reinvent themselves, and some fall apart.
Another experience in love is a quite negative one. Very often love ends by withdrawal of one of the partners. Very often this happens in early stages of love. The reasons for the withdrawal may be perceived differently, but most often it is a disappointment. One of the lovers becomes disillusioned about another, and hopes to find a better mate by searching more.
In many human cultures this is a very sad moment. Often the lover left alone is not ready for the separation. Their love continues and takes diverse forms. Very often the love and longing is so intense that the love left alone is asking the first one to come back, promises to change to better and sometimes threatens to kill themselves. This is a common theme in our culture. I wonder if you can relate to it.
This scenario is often a part of romance culture - it is played out in books, movies, songs and poetry. I have been in this situation many times, most often in a position of a lover left alone. I also asked my loved ones to return, promised to improve and was thinking about killing self. I am not sure whether the idea of killing was my own or whether it was inspired by our culture. Our culture is full of killing, so more likely it was a thought taught to me. My best friend killed himself in such situation when he was 15 years old (with time expectancy about 65 at the time and country). I took it as a very irrational and sad. It was certainly a loss for me which changed my path substantially. First, it prevented me from going far in the thoughts of killing self, and second, I became lonely and hadn't had a close friend any more outside of my family. My family members are my closest friends. Here you can see again, that since we are deaf to communications from higher dimensions, we are lonely and this makes our love and friendship relations extremely important to us. These are also important due to perception of doing this for the first and only time in a single and only life ever.
When I learn about aliens in few limited channeled communications I am always interested in family life in your cultures. For us our family life is extremely important and it surprises and scares us that in many of your cultures, especially in Grey and Grey hybrid cultures the children are separated from parents at early age and are brought up communally. In our system of values this is considered a great loss and trauma for both children and parents.
An interesting aspect of love is its relation to aggression to the point of killing someone. Clearly our culture progresses from being more violent to less violent. Although there is still much violence and death in our mainstream media, there are many people who are opposed to violence and chose a life style without violence. Many people in civilized countries never hurt anyone and even more: people who would not face a thought of killing anyone in real life.
Still, love affairs often face a person with the choice of being responsible in their lover's death. As I said, very often people become disillusioned about their love partner. One of most frequent reasons is that people change with time. Whatever worked for younger people may not work for older ones. People maturate with different speed. For example women age and maturate faster, so with time, they become more mature than their partners and one of the partners loses interest in the relationship.
An important component of love is the confidence that individual's partner is the best of what the individual can get. Very frequent teenagers fall in love when they are still studying and unemployed. This implies that they feel financially poor and are uncertain about their future. Often this defines their personality much. As they finish the study and find reasonably paying jobs, their self-perception and personality changes. They realize that they are "worth more" and can find a better mate. Often people are not even conscious about their desire to be prosperous and successful. The culture promotes this ideal love which is independent of prosperity and success. The culture promotes the idea of loving one's mate only for spiritual qualities. Still, in practice, finances and practical skills of individuals play a huge role in their ability to have family, beget children and keep the family life sound. So the desire for more practically successful mates is either conscious or subconscious, but is almost always present. As the success of love partners changes with time, one of them may perceive that he or she could find a better partner. Often this perception is just a decision that being alone is better than being in the relationship.
In most cases the separation is very painful mentally. One of the consequences of separating is that the only person, with whom you shared all your thoughts without restrictions, often becomes your enemy. Maybe not in physical sense but mentally. In human relationships it is very often that one person wants to leave and another person disapproves of the decision.
I guess, it is hard for you to comprehend how it is possible. Let's figure it out. First, it is a common human practice to attempt to retain your lover even if the lover wants to leave.
Why would a lover try to retain the partner who decides to leave?
First, because it is often practical. Very often humans don't think clearly and can be persuaded one way or another. Attempts at retaining the partner often work. Often it is a case that there is a mistake in judgment by the person deciding to leave. Since there are many humans around it is usually possible for a person to find another partner, but very frequently they overestimate their abilities to find what they imagined. Often the ideals of people are defined by what they see in movies. Often people break relationships and keep searching for partners who would behave and look like movie heroes. This is sometimes successful but more frequently not. The reason for the failure is that behavior of movie actors is very artificial. Only a good part of their life is shown and people often fail to realize that real people almost always have down time and a negative side.
When people are in love and when they separate, human logic is at loss. There are forces of spiritual nature that influence minds and circumstances in ways that are not as obvious in other situations in life. Many people perceive and appreciate the spiritual part of love. Even materialists realize that something magic happens when dealing with love and they relate these supernatural influences via reference to hormonal disbalance, animal instincts and subconscious.
