1- The mutual one : It can be painful after a while and people tend to get back together which does not end well in most cases. This mutual breakup happens when partners fall out of love or come to a realization that they are not compatible.
After the breakup, they genuinely still care for one another.

5) The excuse : The person insists "it's not you, it's me" trying to get you to breakup with them. This is usually when they are done using you so they can jump into a new relationship right after the breakup.
