I received a similar message from an ex-girlfriend of mine who contacted me via Facebook roughly two years after we broke up. She attempted to whitewash the entire relationship and its problems and asked after me. She wanted me to reply to the message to let her know how I was doing but I have no regrets that I felt sufficiently cold to not reply at all as the message just made me quite angry. After all, I rather liked not having to deal with her and I found her message to be intrusive and annoying.
