I'm not as into the dating scene (I like my independence too much) so I'm only interested in a relationship if I see it having the potential of making the distance. (In other words I only date with the eventual intention of making a life long commitment). Call me old fashioned, I don't care .
With that in mind I've only ever dated two people (married one). The first one was a teenage romance (that lasted for most of my high school years). He was an INTJ and incredible. I decided to break it off after school because I wasnt ready to settle down into something more serious. I broke his heart and I still feel terrible about it. We have each other on facebook but we hardly ever talk.
The other one I was married to an ISFJ and unfortunately more in love with the romance associated with traveling and picking up a Canadian man to bring home to my family. The Marriage lasted two and a half years and it was pretty disasterous. We found we were on total opposite wavelengths, he was borning and un-inventive and I was too abstract, non-conformist and a social embarrasment . Needless to say he felt the need to find what he wanted in someone else and when I found out he'd been cheating (again) I decided it was time to leave.
Once my mind was made up I just up and left and didn't look back. It was gut wrentching to the extreme but we ENFPs are adaptable, we survive and move on.
