When you have reached a point of happiness that does not bring complete joy to you or your life, but you are aware that you are in a much better place or situation than you once were.
After a break-up, this feeling is met when you have completely separated all emotional attachment from a person and only have the a small feeling of regret due to all the time spent or, in some cases,wasted, with that person,then you are happierish.
