I am not used to "My husband"

Even though we have celebrated our 2nd anniversary (to tell the truth, we forgot that its our anniversary that day;)), even though we have a baby boy who completed 1 year on our aniversary day, I find it strange to refer my husband as "My husband". When ever I have to introduce him to my friends or colleagues, I simply say "This is Shabu". But sometimes its inevitable and we have to add the phrase -"This is my husband". I have never, not even once, felt easy to do that. I feel some kind of strangeness towards Shabu at that time, as though I am introducing a person who is just an acquaintance. Intially I thought I will get used to it. But it looks like I will never get used to it :)
