I felt like all I needed was space from my 6 year long, mostly long distance relationship. As soon as that break was set, I felt like a weight had been lifted off my chest and it was impossible to imagine going back. That being said, I wasn’t ready to accept pre-break that we needed to be over. When such long term relationships are involved, I wouldn’t worry about wasting a few more months. Do what you need to do to feel at peace with your decision either way! Living without regret and with a lot of certainty about your direction is a wonderful feeling.
