INFPs are sometimes OK in my book. I've dated a few.
The one that I was most serious with is of only average looks, and honestly, I need a girl to be at least a 6 or above. I know it sounds callous and shallow for me to say this, but looks are one of the major departments in how most men qualify women, and I just want to be honest and upfront about it. I broke it off partly because she annoyed me and... her hotness wasn't enough to compensate for it.
Annoying. Now there's another callous word I'm throwing out. I'm absolutely sure I'm annoying to many people as well.
She's probably perfect for someone who can appreciate her depth and charm. But for me, I found it stifling. I know that INFPs are generally free spirits, but the more I got annoyed and distant, the more I sensed her desperation, which turned into a feedback loop. Not good.
She found almost every aspect of who I am a total turn-on. Even when she called me a "total asshole" and realized I'm quite cold and calculating when necessary. But I just couldn't return what she needed -- a commitment to the relationship; I bailed because I knew that in the long term, if I were to stay with her, I'd be unsatisfied because we weren't on the same page with reciprocal levels of attraction. We were especially not on the same intellectual level; she viewed my thoughts and theories as building blocks for attraction, and would respond with some total emotional BS (from my subjective point of view) that made me think she's a total ditz (which she's not, but when I say things like "I think some people are such wastes of life that they should just be rendered into fertilizer to serve society better", you can imagine her F-based reaction).
Hope this rambling sheds some light on one male ENTP's experiences with a female INFP.
