This is done willingly, which makes ADHDers great listeners and advice givers. But if this situation is unbalanced, leading to the ADHDer being always the listener, it can lead to emotional overstimulation. The more intense the relationship, the sooner this can happen.

At this point the ADHDer can disengage from their feelings. This leads to them being missing, more unhealthy hyperfocus, not answering often or as desired, and sometimes even narcissistic and uncaring. In contrast to stage 1 where they were amazing listeners, is a huge contrast.

Emotional disengaging is something that happens unwillingly, but a defense mechanism for the emotionally overloaded brain. Many ADHDers aren't even aware of what's happening, nor can help it. It's a state of emotional dissociation that can last weeks, months, even years.

It usually feels as a state of apathy filled with background muffled anxiety, like a sleepy state you can't shake off. It's hard to realize this is happening, which can lead to (even more) anxiety, depression and, quite often, ruined relationships.
