I'm don't betray even if i get betrayed slightly or completely.

Maybe you're actually a decent honorable person? I like to think I wouldn't betray someone who has betrayed me, but one thing's for sure I don't remain friends with a person who has betrayed me. Certain secrets I won't keep for a person though, if someone is lying, cheating or stealing their secret ain't gonna be safe with me. I had a friend who slept with a married guy and kept talking about how she wanted to see him again and I of course dumped her as a friend. I didn't go out of the way to gossip about her, but I didn't feel like I needed to protect her either. I figure if she wasn't doing something wrong she wouldn't have to worry about people judging and gossiping about her. I vaguely remember her saying something about how she used to think I wasn't judgemental to which I said, "I used to think used to think you were decent".

I don't care if adulterous people get stabbed in the back, I really don't, and I never will.

Ok. Thanks for the update... who ever you are.

Not betraying is kind of vague. I won't stoop to avenge things like backstabbing, unfaithfulness etc. But there's a big risk I will betray the entire relationship with someone if I am betrayed in some ways.
