@Rasp an autistic co-dependent relationship is no more or less toxic than an allistic one, because the problem is the codependence. That's why I said "fight themselves" not "each other". Both partners need to accept themselves and their needs first so that the other person can given them the space to fulfill them. There is no need for one to "handle" the other's needs, there is only need for one to give their partner enough space to breathe and live in. But you need to accept your needs first.
