. He had also NEVER told me how he felt during our relationship, so there was no way of me ever being able to know what was wrong and try to fix it, because I would have been more than willing to do so.
When we broke up, he pretty much unfriended me on Myspace/Facebook, blocked me, and deleted every single post and picture of us.
I'm definitely guilty of doing this. I do it mostly out of self-defense - people can be so aggressive and controlling at times without even realizing it. I have a tendency to get overwhelmed by people who keep expecting and wanting something from you, something you can't or no longer wish to offer. The harder they try, the more I pull away. If someone is having negative effects on my state of mind, or is trying to take away my independence (whether intentionally or not), then I have to put an end to it.
It's nothing personal, though I understand it's often taken that way.
But he did say he felt that he felt like we were bringing each other down. He didn't seem at all affected by the break up, and left it really easily
My INFJ friend is like this too. In certain conflict situations, he finds it VERY VERY VERY VERY VERY difficult to tell the other person what is wrong, why is it wrong and why is he hurting. He would tell other close friends, but not the person he has the problem with. Eventually, he would write the person a very long email.
Before that though, there would be some cold-shouldering where you kinda know something is wrong but you don't know what, and when you ask him he'll say something like he's tired or this or that, and nothing to do with what triggered him off.
Usually the other person doesn't realise how much she/he is dragging down said INFJ by their expectations or their demands. My friend said sometimes he feels like everybody is pulling at his leg, demanding stuff from him, and he gets so overwhelmed.
The blocking and banning from facebook/msn/etc... is what he does when he's already decided to cut off that person from his life. But the cutting-off by an INFJ is not the same as the cutting-off by some other types, because I think the INFJ would usually still be willing to talk to the other person and would be more receptive to being friends again----AFTER they have made peace with the inner you (who they had the conflict with) in their minds.
On the other hand, my ISTP self would already be gallavanting to new lands and forgot that she automatically filtered all your emails to the spam box... and she probably lost her cellphone too so you couldnt call her... and she has multiple google/msn accounts.... and well... she would talk to you, but the experience she had with you has already been incorporated into her broad and all-encompassing Ti system and now, oops sorry, can't talk to you anymore, have to go... uhmm... for an appointment... yes... bye! have a nice life!
Oh, and i find that that the people INFJ "cut off" with, sometimes they still try to maintain some Fe civility with in social contexts---like saying hi and bye, or just small talk. With me, it would be a complete ignore if i found myself in a situation with them...
