Yes, yes, and yes. I know I'd be very much like that. . . the whole "dating around until I was committed, and then once committed always there."I've been married to an ESFJ for nearly 10 years and I don't think she has ever thought about cheating. The key word here is "married" which is on a higher level that "in a relationship". While we were dating she wanted to play the field as much as possible and not tie herself down to anyone. Once she decided she really loved me and that she was willing to marry me she settled down and gave her whole heart to me. Now she tells me that I've ruined her of any other man.
However, I might also add that we both come from a very conservative background and were not sexually active during the dating phase. So when I say she was playing the field, I mean she was sucking face with other dudes and then still wanting me to do the same with me. I could not tolerate it and it was a huge problem during that time in my life.
Dating an ESFJ was one of the most miserable experiences in my life. Being married to an ESFJ has been great.
That's the way I am. . . there's nothing holding you down until you love them and you've committed.
