Me: INTP. Used to date an ISTJ, and boy was that a relationship laced with miscommunication about perceived ways in which we should behave (he didn't like my sarcasm and nothing was ever his fault). I wish I'd had some knowledge of MBTI back then, I could have used my knowledge to maybe bridge the gap between our personalities.
I've also dated an ISTP, which was closer, but still not all that great. Still searching for the right one, but there's no telling who I'll be attracted to.
