My previous serious relationships were with a 2 and an 8.

2 felt needy to me, and I seemed very cold to him.
8 smothered the heck out of me, and sees me as rebellious and in need of direction. (parent/child feeling).

The 5 is the only one I have ever truly felt understood me and does not misread me or my intentions....and from what I have gather most of my life, I am misunderstood in general because I am not putting out the standard/expected 'vibes' in life.
It has drawn me very strongly toward him.

Maybe some types need to be with like types, and others with opposites.
There must be a type of formula of sorts.
