I've got an ENTP friend who's in a long distance relationship with an unhealthy ISFJ who she's said is at sometimes suicidal. She's really struggling with what to do as he's wanting a long commitment that she's not sure she's interested in.
Then I came along. And while I'm giving her counsel, we're starting to show interest in each other.
To ESTPs: In general, what are your experiences with ISFJs and INFJs in relationships?
To everyone: How does one deal with an unhealthy person and ending a relationship?
