If it helps at all, I had the exact same experience with an ENTP. Broke my heart into pieces not long ago, still recovering, but now everytime I see an ENTP i feel an overwhelming sense of self-hatred.
From my own observations there is a pattern here for unrequited love (INTJ, ESFP >INFP, ESTJ; INFJ, ESTP > INTP, ENTJ; INFP, ESTJ> ENTP, ISFJ; ISFJ, ENTP>ENFJ, ISTP etc.)
offcourse this could all be my overactive Ne tryin to make sense of why I could possibly not be alone in what I feel.
