Woah, woah, woah... ALL of my old friends (a group of around five) showed this kind of behavior. I always knew there was something really wrong with them, things were unfair, every conversation I had with them was draining because of so much drama going on.
Two of them had ALL of those characteristics, while the rest had more of the 4, 6, 7, and 8. One of them had A LOT of the number 6. it was impossible to talk to this person about a problem without him going "yeah, and I have heart failure" then tell me how they're about to die.
Back then, I was naive and stupid, so I trusted them. It was the most horrible stage of my life. I was a slave of this group. When I met my actual friends, then I realized how the others never really gave a damn and they didn't deserve to be called friends.
But there's one thing, Remus. I was left very paranoid after those relationships, probably because they lasted long. Not to mention that my family, especially my brother, showed this behavior as well. I have some trust issues. You say in your post to trust your gut, but what should I do if my gut isn't always a reliable source?
I can tell you right now, that neither my mate or friends have ever done anything of this. They're all the best people I could ever met. But when I think too much, I start thinking "What if...?". For example, a thought that comes to mind often, "What if my mate turns out to be abusive later?". This concern comes from my mother's experience. My father wasn't abusive, he became abusive MUCH later, after they got married.
Trusting my gut has saved me multiple times from people who wanted to take advantage of me. But being this wary all the time does no good at times. What do you suggest?
