None of the people who've blocked me or asked me to not contact them have been my ex-girlfriend; I have only one ex-girlfriend, and we broke up on good terms. I have occasionally "*****ed" about other people who ought to have no reason to block me blocking me or otherwise treating me like filth, but not my ex-girlfriend... although sometimes I may have speculated---worried, even-- that she's deliberately not responding to some of the comments I've made... then again, I know she checks her Facebook account infrequently enough that it would be easy to miss them.
So yeah, I say "Derp" now.
