Now that the Frozen song is stuck in your head....
I recently shared my experience of being completely betrayed by a "friend". This person lied to me, manipulated me, used me, made excuses, and then actually had the audacity to blame me for his blatant inability to keep his dick in his pants. He was stupid enough to think that two women - friends at that - wouldn't talk, compare notes, and realize that they were both being played by the same ignorant, lying pig. How's that for being delusional?
I have a tendency to always want to process everything; to be able to understand it, organize it, wrap my head around it, and put it in a neat little box. Sadly, sometimes that's just something that can't be done (as is the case here). You simply can't justify someone's reprehensible behavior. There's no amount of explanation that can make you understand it; you just can't fathom that someone would behave in this manner. It can be impossible to comprehend someone's actions or motives; try as you might, sometimes you just can't make sense of things. Maybe that's what separates the good people from the bad.
Here's the thing - this guy's inability to take responsibility for his actions is his shit, not mine (there's something to be said for accountability, huh?). No amount of arguing or reasoning with him is going to change anything. You can't rationalize with or force someone to see the err of their ways either. The only thing you can do in this situation, for the sake of your own sanity, is to let it go. Move on.
While you don't necessarily have to accept it, you do need to recognize it for what it is - something you can't change, nor take personally. People are fucked up. We don't always act in the best interest of others - in fact, we rarely do; we're selfish creatures by nature. This certainly doesn't justify or excuse it - it's just a fact that we need to remember so that we can deal with the bullshit, pack up our pride, and move onto something better and healthier.
Bottom line - people are going to come into your life that are going to be wicked and evil. They'll lie, cheat, steal, and hurt you more than you could ever imagine. Unfortunately, this is just an inevitable fact of life. Nothing will ever prepare you for it and it may very well be impossible for you to understand it. In moments like this, I believe we need to have faith in and trust the greater good, and just let the rest go. It's the only way to move forward and stop them from dragging you down to their level.
