"The writers say that Bellamy doesn't trust himself to make decisions without Clarke and I think that she has influenced him positively (particularly in Season 1)"

And this is what I hope happens with Clarke taking off is that Bellamy realizes that Clarke set him on the right path but he's a leader in his own right and he doesn't need her by his side anymore to make good decisions and gains trust in himself. (I actually hoped he had already learned this from his time spent being a bad-ass spy in Mount Weather, but I guess not?)
