when you've made progress- maybe made some good choice, like getting out of or over an unhealthy relationship, only to get swept back up in the sentiment and old habits, I'd call that 'abandoning changes.'  Well, other things as well, but I think my favorite g-mail's name for 'moving on' before sending or saving a draft fits appropriately.  Dart through my heart.  I like my life.  I am happy.   There have been only brief moments of relapse lately for me.  And I don't want anything different.  It's just been a flittering thought- me in another alternate world where things turned out differently.  Then I open my eyes a little wider and am glad life didn't go that way.  I like that it can be bigger and better than my mind dreams.
