The deal is it’s not really about reunification with your abuser, in cases of severe abuse you wouldn’t be reunified with someone who wasn’t fit, you’d remain in the foster system. In cases of milder abuse, a judge has to weigh whether the parent might be rehabilitated or you’ll be better off staying in the foster system, which is always itself a risk, remember. Foster families are not always the best.
Reunification therapy is also for divorce cases though, where one parent has essentially poisoned the well against another with no real abuse being present.
So, uh, sorry for whatever happened to you, it can be a very difficult situation when a child has nowhere else to go. Depending on availability of foster families, a judge may be forced to sometimes make a difficult decision, it just depends on the circumstances.
