Just in general?
And perhaps with online interactions (facebook for example) too
For a specific scenario, I liked an INTJ then he liked me back but due to unfortunate circumstances it didn't work out, but we still liked each other for a long time afterwards (despite it not working out due to circumstances, we got a long very, very, very well). Recently I tried blocking him out because despite my feelings, I think that it really won't work out. Now we don't see each other IRL much but I'm hypersensitive to actions (being the ENFP that I am) I've noticed that his online interactions with me have spiked (although it is really subtle; the PerC equivalents of his online interactions with me would be him giving me loads of 'thanks' all the time) and this never really happened when we used to talk IRL and on chat like we did before (nowadays we don't because I'm trying to block him out).
Is he trying to get my attention again, or am I just being hypersensitive and is he actually over me?
INTJs can be so hard to read...
Oh and if he has a PerC account and/or is reading this I am doomed for sure. Oh well!
