fusion

The lesbian relationship classic: two people get so emotionally intertwined so fast that the line between 'me' and 'us' disappears. Shared friends, shared schedule, shared feelings, often a shared address within weeks. Sister concept to the 'urge to merge' and U-Hauling. It can be sweet closeness or full-blown enmeshment where nobody has their own life anymore. The term's been kicking around lesbian therapy circles since the 1980s and the wider sapphic internet runs with it now.
