Is it wrong to still be sad about a divorce?

I've been separated from my husband since Nov 07' and our divorce was finalized in Jul 08'. I am still sad about it and really sensitive. Not on a day to day basis, but when I stop to thnk about things or talk to him, I still get all chocked up and teary eyed. My every day life is normal, I've met a lot of cool people, but I am not ready to 'put' myself out there. Is this normal? Divorced people, how long did it take you?
