I think most of us can be abused only so long.
I don't know if it is useful to call it good or bad - it just seems like the natural result of someone abusing a relationship until there is nothing good left in it.
And I also think it is a way our mind protects us from further hurt. I think it's like being in shock, we might be hurt but we don't feel the pain because our brain shields us from pain that is too much to handle all at once.
I think the antidote is to follow through on getting yourself free and then finding a nurturing environment in which to heal. In my case, it took a lot longer to heal than I thought it would.
Prayers for your future happines.
