Does it mean a lot when a guy cut his hair for me?

I Facebook my ex boyfriend "you shud cut your hair. I think you look good in short hair". He doesn't have long hair just that I like it when he shave his head. We've been broken up for a long while now but we still work together and are in good term I guess. It's awkward sometimes. Anyway, he did cut his hair and my guy friends thought I should ask him out already but I don't know if its a good timing. I guess it does mean something since he care about my opinions. What do you think?
