If you are in a toxic relationship with someone, it's understandable and actually for the best to minimise contact. Parents or not. There's no need to idealize ALL parents because not all are good. We may all have read/seen incidents where parents do terrible stuff to their kids. Respect is not involved. It's simple reality. Getting some space away for your own well being. If one is yet to be financially independent, they may face some money issues. Use time away wisely. One can keep contact to the level they are comfortable with eg by phone. It's a parent's duty to give their kids stable & peaceful environments and one should not feel guilty of looking for them.
