Last Names

So I've been married just over 6 months now. And with all the adjustment periods and getting used to sharing, doing, discussing EVERYTHING with my wonderful husband when, up till now I'd been Miss Independent, I find the most difficult transition is..... using my new last name.
It's not that I forget I've changed it. (Ok, sometimes I do.) It's just plain difficult to remember to USE it! When people ask you your name to fill out forms or whatnot, after 34 years with my maiden name I'm realizing just how difficult it really is to use my husband's name... though I so desperately want to.
What adds to my difficulty is this. My husband's last name is Greek. Neither of us are Greek. So when someone asks for my last name and I give it, it's cause for second takes. The fact that we are both of Scottish/Irish descent only adds to the confusion as people now try to SPELL it. It's not actually that difficult, but it's not a common name, and there's an 'x' in it. I think x's throw people right off. The name is spelled exactly as it sounds, but for some reason everyone gets all the letters mixed up and even add a few of their own for good measure.
I'm proud of my new last name, but sometimes it's just easier to use my maiden name. I know this really bothers my husband. But I try to explain to him that it's not all that easy to just start calling yourself by a new surname. He didn't have to do it, so it's hard for him to understand. I'll get it someday... I just need a little more time. Regardless, there's no one else's name I'd rather take.
