In part, yes, sex. The event I refer to was BDSM in nature. So when I say play I mean it in that sense. That, of course, can be sexual and/or lead to sex but not necessarily. Also, the primary reason for the open relationship was to be able to “vent” / explore sexually where one partner was not able/interested in doing so. I can separate sex and love but I cannot separate commitment and intimate exclusivity (to sound off one of your quotes). I believe him when he says he can love more than one person. I believe him when he says he is committed to me. But I am unable “to share him” (as he puts it) on the intimate level.
