Answer: usually is understood under symbiotic disorder the fact that two people have a relationship where the one is for the other the only and sole absolute principle, so that the world disappears as such as value and family, friends, work boundaries disappear in their behaviour determining meaning. State of psychological researches around 1980 (mainly USA) maintain that a symbiotic disorder can’t be regulated if another, third, affective factor does not appear.
Symbiotic relationships are known as extremely violent, passionate, autistic towards the outer world and even self distructive or distructive.
Nothing specially nice.
Personal researches on the subject allowed to draw the personal conclusion that symbiotic relationships are based on the thought or awareness of a ‘forbidden’ boundary, that links people together through the ‘evil’ of the unconscious, making appear all sorts of ‘perverted, radical, extreme’ behaviour. Thus very often the case in female homosexual relationships and in mother/son relationships with incestual tendency. The fact that these are rarely the case in homosexual male or father/daughter relationships, may be a hint for the fact that affective relationships show specific characters depending on their nature.
Further, I went on distinguishing outer symbiotic disorder (as before mentioned) from inner symbiotic disorder, where the structures of understanding fuse with psychic mechanisms, giving birth to an extremely strange configuration of reality that is often confused with schizophrenia and though also the origin of extreme talents (type Mozart). It may be possible that inner symbiotic structures are at the origin of outer symbiotic disorder.
It is also possible, I think, to heal symbiotic disorder through a therapy implying the awareness of moral consciousness. To say: it is perhaps socially correct to say that homosexuality is a ‘personal choice’ without moral implications, society and thus our personal moral awareness does mostly say the contrary. A possible justification of a homosexual tendency may put a frein to a symbiotic relationship. In the case though of incestual tendencies, the problem is not that easy, as I don’t think there may be any justification whatsoever, even as disposition. It may though be possible that a reinforcement of a certain number of structures of understanding and the reinforecement of auto determination stop also this kind of symbiotic disorder.
Studies are little on the subject, though, even less on my theories, which though have shown quite effective in their private maintainance in personal relationships.
The increasing number of symbiotic disorder in heterosexual relationships is, to my understanding, due more to the imitation of former structures that are praised by some as the summum of love and passion than to intrinsecal structures.
