How well do you know your Husband?

I like to believe that I know my husband very well. Half the time I know what he is going to say and do before he does or says it. We have been together for 6 almost 7 years and have 2 kids together with another on the way. We are also in the process of buying a house. I think if he was hiding any skeletons in his closet they would have come out before now. I found only one thing in all these years that sent for a loop and that was when we pulled his credit report because we are getting ready to buy a house and there was a past bill on there from a jewelry store when I began to inquire on what it was I found out that he had bought a very expensive necklace for an exgirlfriend only 1 year before we got together. I bothered me a little and still does at times because he never bought me an expensive necklace but that was in the past and I have the big fat engagement ring to prove that he loves me.
