Michelle Williams and Spike Jonze

Surprisingly Michelle Williams, who was married to the late Heath Ledger and has a daughter by him, is dating again already. 

Does this mean that she was not really in love with Ledger? Or maybe that she was, but has an extremely resiliant character?

It's anybody's guess. But it does seem to be quite an interesting development. Some women (and men, for that matter) take years -- even decades -- to get over the loss of a partner and find love and romance with someone new.
