I have always been a bit self-congratulatory on my seemingly developed Fe (for an INTP) - I've always gotten what I wanted in relationships and have only rarely been lonely and/or disconnected or had issues saying what I felt or being appropriately demonstrative when needed. I've also rarely been unhappy in relationships, even those that ended, and have never, not ONCE, had the desire to cheat on a partner.
With that introduction, I just cheated (big-time emotional + physical over a few days on holiday) on my long-term INTJ partner with (I am fairly sure) another INTP.
This was so out of the blue and unanticipated, and so very very damaging to my own feelings about my current relationship that I'm now thinking that my supposed self-confidence in my emotional abilities was all overconfidence and basically crap. Has anyone else had a similar experience? I thought that INTPs were supposed to be good at analysis, but it seems in this case I had a LOT of repressed shit going on that I really had no conscious knowledge of. Or at least that seems to be the case assuming that hardcore falling for someone you hardly know doesn't come out of nowhere.
Right now I'm stuck in a bit of limbo about what to do but it's not a state that can last.
