As long as I can remember, there have always been unspoken, but what I assumed to be, understood codes. These are basically codes of ethics that apply to certain situations and relationships. In the hood, we follow street code. So for instance, under no circumstance do you smash your dude's girl. Nor do you rock with the enemies of a friend. I bring this up because in relationships of any sort, we all have this mutual understanding that's never explicitly stated. The problem is, not everyone understands this.
My close friend had a dude she used to jump off with, but later found out he became involved. The problem is, the dynamic of their relationship was such, that they both understood they were "homie lover friends". LOL. So when dude didn't inform her that he was getting involved, she felt betrayed. Not because she wanted to be with him, but because they were cool enough that he could have kept it real with her. She shouldn't have found out through 3rd parties or through other means. This is a perfect example of code being broken. Based on their relationship, I think dude is lucky that homegirl didn't do something malicious because she may have been justified in doing so. Their "code" of trust was forever broken.
Thing is, when you break code, you have to accept full accountability for the consequences that follow. I've seen ass whippings and even more violent acts handed out because of code violations. Point is, never expect things to be the same once code is broken. If you value your friends or whatever relationships you have, be cognizant of the unwritten, unspoken rules that govern your bond!!
Just my thoughts...
