Companionate Breakup

the collaborative, amicable and (ironically) emotionally connecting ending of a relationship done when emotionally mature, emotionally healthy people respectfully acknowledge their differing wants and needs and agree together within a context of mutual respect to end the aspects of their relationship which do not serve them, sometimes enabling them to part as friends with love in their hearts.

Mature people in love who find that they just aren't right for each other don't have to find some bullshit reasons to hate each other to justify ending the relationship, they can recognize what isn't working and communicate, to have a companionate breakup.
