well it certainly is not going to help either party if emotionally detached attracts the same. whether conscious or not, we are always seeking balance. if one is sufficiently balanced, they are strong enough to carry unbalanced, and balanced assisting unbalanced reinforces balanced.
much of this all occurs subconsciously.
in my case, i was quite young, in my first LTR and it took a very traumatic life experience during our relationship causing my ex-boyfriend to completely detach from emotions. it was the only way he was able to cope. our relationship maintained, around his emotional breakdown, until he could climb back up to his emotions which will likely always be scarred.
before and after this traumatic time, i think both his strength and curse is his independence and i find the same to be true of me. relationships are surely meant to give you clear glimpses of yourself.
