I'm entering into this discussion late, but I'm also an ENf/tP. I started out ENTP, am now ENFP and have been for some years. The T/F is almost a 50/50split similar to yours and the last test I took I was ENTP again.
Like you, in highschool I also played devil's advocate and loved debating and would do it with teachers as well as students. I was known for "thinking [i] could out argue anyone" and other students would sometimes ask me to argue with the teacher about assignments or tests (basically to get out of them or get an extra point about something). Perhaps it's our borderline T that gives us that? Law student friends and those that deal with law have told me I 'think and talk' like a lawyer at least when it comes to covering my ass and I should consider law school.
I have to say though, I was surprised at how soft and huggy and non-assertive ENFPs on this forum seemed...I had no idea we were this easygoing and sappy!

Aw, you know I love you...which is to say I love me...

(is this ENFP enough for you?) Though I take it with a grain of salt and understand how a forum can be a much welcomed place to unload and commiserate --truthfully, some ENFP comments did make me question the validity of my type...
Maybe I wish I were tougher than I am?
But when it comes down to it no matter how much people tell me I'm a 'nontraditional female' (opinionated, bossy, assertive, direct, etc.) or how strong I think my 'T' may be getting, at the end of the day I just really want people to
like me and for everyone to get along and be the best they can be and everyone to be happy and reach their dreams.... and be entertained and warm and fuzzy!' etc. etc. etc. DEAR LORD. Even I am aware how sappy this sounds.

And I like puppies and babies????
Anyhow Jake, I think you get my drift. You may have a strong T or even a competing T to your F, but if your gut directive is to care about how people *feel* and you always want to be sensitive to feelings and warm fuzzies

, you are probably predominantly ENFP. Also, at the end of the day if you are able to let things go even though you
know you didn't get quite your fair share or you gave someone too many free passes or someone took advantage of your kindness just a tiny bit -- but you don't care and are more just very relieved and relaxed and happy that everything is over and relationships are harmonious and you breathe a sigh of relief -- you are probably an F.
Also, if you know any ENFPs or ENTPs IRL to compare yourself to, I think that's the most helpful. One thing that definitely colors my self-interpretation is that while I did NOT identify with either the 1 ENFP or 1 ENTP (also women) that I have met -- the ENTP annoyed the shit out of me. It was like she was a child acting out for attention and acted like she was either in competition with me or actively trying to embarass me in public.

And I really did
not want to aspire to her personality...(unless it's natural for ENTPs do dislike one another?) The ENFP? Even though we'll never be friends I can get along with her much better and I can see why she is a well-liked person.
