I'm sorry that sort of thing has happened to you and although I know you certainly will get past it, that doesn't change that it hurt.
I sat here for a few minutes and tried to think over my life to find some sort of story of when I took revenge, but I couldn't think of a single time. If I ever did, it is long forgotten.
That doesn't mean I have not been hurt or done wrong, because I have. Normally though, I walk away, for good. I never cared much for very negative drama and a few times it took a long time to come to peace with whatever it was. If it was a truly ugly offense, that person didn't get a second chance to do it again to me.
I'm very non violent, but that does not mean I would not take up for myself (or try) or that I would not jump in however was necessary if someone tried to mess with someone close to me in my presence.
I do believe in a sort of karma, maybe not exactly as the word usually is taken, but kind of. If someone lives a life of abusing others or deals out some other sort of negativity all the time, sooner or later they will do it to the wrong person and someone will lay them out for it...... or they will end up very alone.
Yeah me too but it's not the first time and I guess won't be the last; what's fortuitous is that it didn't end me and I'll get around it.
It's good practice to walk away from those who do us wrong and I'm one who, once trust is lost or the harm is done, will never allow that person back in, certainly not in the same way as previously. The degree of the shutout is dependent on the damage done.
I'm not one for karma, I prefer positive action, but for sure I understand what you're saying; those who live that sort of life sort of attracts the same.
