Interesting question Unpredictable!
I have thought about this many times, and have discussed it with my close friends. I once had a friend who expected people to always come and go through her life. She would say that people come in at certain times and that no matter how long they were in her life, what mattered was that you had certain experiences with them, and that she learned and grew as a person, even though they would not always be in her life. For me, I never understood why friendships would fall apart. When I let someone close to me, I never want them out of my life. I believe that true friendships are the ones that last forever, no matter how far apart two people are. Over the years I have had people that were once close to me, slowly distance themselves and leave from my life, and though it makes me sad, I have come to accept that there are only a rare few that will stay. However, one thing is for sure, I cannot go into any relationship knowing that it will not last forever. I am realistic, and I realize that we can never know, never completely expect things to go our way, but when I let someone close to me, I must know that I can trust them, so I will not expect them to leave. That is why I don't let people get close to me too easily. I have a bunch of friends and acquaintances, but the ones that I consider my true, close friends, and loved ones, are the ones that I know will not abandon me. I pick up on vibes from people, and I often know from the beginning which people are going to give me their loyalty. I have had a few friends in my life that have stuck with me for years, and those are the ones that I truly value and adore. I am currently single, because I cannot have relationships for the sake of having them. I find it very hard to fall in love or become attached, but when I do, I become so attached to that person, I feel that they are mine. I will never let that bond break...I have only fallen in love once, and though that person is out of my life at the moment, I still feel a bond with them that will never break.
