a relationship of mutual respect and mutual stubbornness - it wasn't a significant other, just a friend - they are pretty rare too like INFJs and INTJs
in my experience they are quite outspoken, may be insensitive, and can be a bit overwhelming as extraverts, usually their talks are centered around "lets do it this way" "why didn't you do it this way?" "what do you think about these plans", they are more collected and organized, and they will want to debate with you if you haven't done things the best way, which to them is most efficient and logical way - if you just keep quiet, avoid the argument but also not do what ENTJ has told you to do this can lead them to get upset with you
