Sounds normal to me. When I divorced my wife after we were seperated for 6 months, I knew it was the right thing to do. But its taken 2 years to completely get over it. Even if you don't loved someone anymore, you get used to them and having them around. In my case, I tried to stay friends with my ex-wife, but that didn't work out. Probably made it worse for me in the end.
Good luck, I hope the best for you.
Cheers,
Mike
