I would say 7 and 4 is a hot and cold dynamic. Initially, the 4 is attracted by the 7’s ability to show them a whole new world and the 7 is attracted by the 4 being one a kind as manifested through the 7’s fixation on shiny objects (7 thinks, “Wow, you’re not boring like everyone else!”, essentially
). But eventually they begin to hate each other for the very same reasons... Personally, I was never more miserable than when I was in a relationship with a 4. It was basically just me giving unconditional love to the 4, who hated themself immensely, the whole time without any return and I grew to despise their “I’m so speshul nobody is like me im an alien l0l” attitude. And they were very jealous over me being an extravert with a wide range of friends and for being attractive and so forth.
I think 7 has a much better lasting relationship with a 9, who is also sensitive but withholds it and doesn’t build their life around it.
OP, I would say tread carefully.
