I don't have much to add here that hasn't already been said but I did experience something similar to this in the past few months. There are 4 scouts in our den that have completely dropped off since December (around the time the other den leader completely quit pitching in, who was a good friend of all their moms.) They all re-chartered via our Cub Master but have nothing to do with me. No responses to phone calls, texts, emails - I let them know of everything coming up and never hear anything in return. At the B&G, none showed up but our CM still had their Tiger patches ready (even though they did not complete half the achievements.) I realized at that point that nothing I could do would sway them, either they'll come back or they'll eventually drop out altogether (per advice of others and the writings in here as well.) I wish you luck with it, definitely try not to take it personally. I did for the first few weeks but as my husband pointed out, its for the boys, you can only do so much and not everyone who joins sticks with it (he's an example of that as he quit early on when he was a child.)
