I see it often in people on the spectrum and I had this issue for a very long time, as bad as it gets, the involvement takes over, so my theory is that dispersing involvement between multiple partners will not make me lose my mind as much. It works until it doesn't. Hit and miss. There's always the chance of getting overly involved. Also ignoring life commitments and self care. This can be problematic like a super deep autistic special interest in a person and can shift into unhealthy, perhaps if I start expecting too much from a person.
