Betrayal of trust? Drama much? Nah, betrayal is when your "friend" sleeps with your wife. This is just a damaged possession. Not even one he's too worried about. You seem to think it is an attack on him personally, but he doesn't seem to take it that way. I'm sure he knew ahead of time his friend was capable of bizarre decisions.
Fair enough, my language was stronger than the point I was trying to make. I've been caught in similar situations that have still left me bitter. And I've seen plenty of situations like this where something that seems small eventually causes much larger problems. The only people I've trusted twice are the ones who have done the most damage. Trust is a funny thing, and it's crucial in any relationship. It may not have been a direct attack, but lies of omission, lies of commission, and a brazen lack of mutual respect are just as unacceptable. It may just be his back up bass now, but if things continue this way (as often happens once a relationship falls into that swing) it could end with significantly larger consequences. On the other hand, it could just be this one instance. This is all just conjecture, but like I said, I've had to train myself not to trust anyone more than once. Psychologically speaking, you're just nurturing a potentially destructive relationship.
It's something I've seen a lot, and from the experience I've gained through my own misfortune, I only have the OP's best interests at heart. I've lost quite a lot, and I think that the OP could avoid further loss by sternly reconsidering what is means to be a friend.
No, I'm not anyway. My first priority is to God, then to my wife & family, then to country, then to myself, then to my friends and neighbors. I could go on, but suffice it to say, my basses are way down the list. They are luxuries. Maybe at 22, you can be your own priority, and maybe that's good, but as time marches on, others things become more important.
My basses aren't high on my priority list either. And with the exception of God, the rest of your priorities aren't really mutually exclusive with yourself. Heck, even your priority to God can be considered for yourself - the goal being eternity in heaven, in bliss, free from worry or pain. I too am Christian, so I know that I'm oversimplifying here. But be aware that we are all a product of circumstance. We all operate under different conditions with different sets of tools. But trying to remove yourself from your environment and look objectively, life is about living. We seek peace, happiness, and generativity for ourselves and for the common good, yet these things are not requirements - "luxuries," you might say. I understand the idea of forgiving and forgetting, but I also understand setting yourself up to fail.
Granted, I don't have a wife or children, but you really can't say what my own priorities are. I don't have to explain them or defend them or try to justify them to anyone else, and trying to compare them is an exercise in vain. The point is that whether you acknowledge it or not, your first priority
is yourself. Everything you do is based on your own desire. Even things that you may not "want" to do, you endure because they yield the outcome that you
do desire. So even as priorities change throughout life, they all revolve around perpetuating yourself, your safety, or something that will ease you. It's okay to admit it, because it's what keeps us alive to do God's work or defend your country or assure the well being of your family. It's what drives us to do anything... and everything.
I just think that the priority here would be to remove yourself from a situation that in all likelihood could continue or possibly get worse. I'm not saying that you shouldn't forgive the guy. I'm just saying that being around people like that isn't healthy. You don't necessarily have to end the friendship completely and sever all ties. But you need to realize that this person isn't the kind of "friend" you really want to be around. Even the Bible says to run away from situations that may facilitate sin. And again, psychologically speaking, once a behavior is reenforced in a relationship, it generally reoccurs. People may change over time, but usually even if two people have spent a wealth of time apart, their relationship will pick up right where it left off, whether it's positive or negative.
It may have been just a bass, but the way the "friend" reacted to the situation really changed the entire dynamic. The bass may not have meant that much to the OP, but the friend went through a lot to disguise what actually happened. What makes you think he won't do that to things that actually matter to the OP? So many people have stomped all over me for my tendency to trust people or be optimistic that I've had to learn to discriminate what I really can or cannot trust. In doing so, I try remove myself from negative situations or relationships before it gets to ugly - because they do get ugly.
