My boyfriend thinks I'm an INFP, and some tests say I'm an INFP, but I don't know if I can fully be described as an INFP.

For sure, i'm introverted. However, I question the NFP part. It seems to me like all I*** descriptions describe me in some way. I was convinced I was an ISFP for a while, but now I'm not so certain.

How can I be absolutely sure what I am?
