Re: INTP and INFP?
There are specific hurdles: You're introverted thinking, he's introverted feeling... that's likely to cause misunderstandings, because you'll be doing thinking and he'll be doing feeling- and both of you will be keeping it to yourself. The key is to share a lot, much more than you usually would with friends.
But besides that, there's not much to worry about. We're pretty compatiable.
I <3 INFP girls. They are wonderful mysterious creatures...
