I wonder whether you lost your 15 pounds because of
feeling all those stupid, pointless, ridiculous feelings one feels when one's partner finds happiness with someone else
Nah, correlation and causation problems here... but most of the info came during the diet, so you could try and force feed that argument (pun intended). I mean, she found happiness with other people for a few nights, but we still find happiness together, maybe I made it look like I was left too, which was not the case, kudos on dealing with your thing though!
As in Joshua Blaine's original description (below), but may be used to brag about things you've accomplished either this month (January) or the previous one (December), assuming that you haven't brought it up in any earlier Monthly Bragging Thread.
