i can both agree and disagree .
in one hand usually when you two go separate ways it means something made you / them realize its gonna be a disaster in the end and it might be for the best .
on the second hand , i left my best friend because of a political argument and because they were being a dick to me . but then i did exactly what you said . we havent talked for *2 years* and i reached out , and now theyre my bestest friend ever again . we just both grew into better people over those 2 years , accepted our mistakes , respectfully agreed to disagree on some topics an thats it .
that said , it really depends on how important they were to you, on what terms you decided to stop communicating , and why .
