As South Slavic people yes we are related. We used to be alot closer once upon a time. Many Macedonians looked to Bulgaria for salvation, particularly during the dying days of the Ottoman empire and during the Serbian occupation. Due to historical circumstance we have grown apart. Bulgarians need to respect Macedonian wishes to remain independent and our ethnicity and language to be respected and recognized. It is a matter of accepting reality, regardless of how and when we got there. This lack of respect and recognition is the main reason for any animosity of Macedonians towards Bulgarians.
