I'm a 5w4(female), and I am currently interested in a 7w8 (also female). I've been looking into her type a lot since I suspected she may be 7w8, and I am seriously intrigued. It sounds so fun! And I'm looking forward to the challenge as well. I don't think I would have been prepared if not for my last long term relationship (which was with a volatile 6w7) followed by a dating turned best-friendship with a 7w6.
I definitely have a soft spot for Fours, but feel like they can be just TOO submissive sometimes, I like being dominant actually, but also loved the tables flipped on me...
I love that 7w8s are independent, don't NEED to be in a relationship (like 7w6), and are still playful and fun, and less dominating than an Eight, but still with the ability and tendencies.
My Four wing makes me far more passionate and emotionally in tune and expressive than a Six wing would, while my dominant Fiveness grounds me and allows me to detach from the helpless romantic in me when needed, so I guess I am a not-so-helpless romantic xD
I've got a bit of that Eight in me for sure, I feel like I'll need it to take on the Eight in her, and I LOVE that. Anything that encourages my Eight to emerge is good for me (at least in that respect.) I'm looking forward to seeing how this goes, but I definitely see great potential for a 5w4 and 7w8.
I also noticed that whether a 7w8 or 8w7, the subtype would most embody my strengths AND weaknesses, as a Five, which is fascinating.
However, I'd be more interested in 8w7 as a challenging friend, and 7w8 as a romantic interest.
I've been finding that "missing key" to the Five in the higher levels of the Seven lately as well (and have my 7w6 bestie to think for inadvertently guiding me to and through a lot of it), been quite the Social Butterfly apparently, which is new to me. And need to work on integrating that to Eight... I feel like we'd make a great pair for my continued development, as well as being good for her.... though we will see
She likes my intelligence (as well as humor and dark humor and sarcasm, etc - I like to debate and argue for fun like a 7w8 as well, so I'm looking forward to that muahahaha) and she has humored me in regards to my passion of the Enneagram so far, thinks it's "adorable," so that's fantastic.
Mostly speculating, as things are only beginning... but man, when we kissed last night I was on fire. Looking forward to more of that passion for sure.
