Verbally and/or emotionally abusive
relationship in a throuple format. Can lead to couple team with one wo/man out. Elder throuples can not break from a BTS situation. BTS seems to be most pervasive in the elder communities. Can sometimes present when a 2 elder couples are close and 1 spouse passes or a couple simply is
looking for a third wheel. Eventually
the third wheel is entitled to other wheels and this is when BTS becomes obvious. The cure to BTS is somehow returning to a traditional couple. In elder communities this cure seems impossible to obtain.
