Getting broken up with sucks—especially when you’re completely blindsided by the news. Oftentimes, when you look back on the situation months later, you realize that there were actually plenty of warning signs that things were on the rocks. Maybe you ignored them, hoping things would get better with time. Maybe you even denied them, avoiding the subject altogether.
Either way, I bet we can agree that, had you identified and dealt with these issues head on, you may have been able to repair the relationship or at least end on better terms.
