Yes. The problem with giving help or advice to some people is that, even when they ask for it, they refuse to accept it, try to reinterpret what was said to mean something else, and point blank refuse to acknowledge what is right there in front of them - even when what they are saying in reply cannot logically be true. It can be very draining at times dealing with that and sometimes you just need to distance yourself from them to recover. The hardest part is making them understand that you don't hate them and that you're not putting them out of your life forever, but that you just need that time to recuperate.
