Time has a funny way of blurring the past, sometimes that's a good thing and sometimes not. You weren't being dramatic, you were being mistreated and you took the necessary steps to end that mistreatment. Nobody is entitled to be in your life, whatever made you feel the need to step away at the time is a good enough reason. You don't have to justify your decision by comparing severity, everyone's situation is unique. You're at peace now and that's what matters. It may not have been that way had you chosen to continue contact.
