When we argue my husband says he feels he is being cross-examined and he hates it?

He says I fire questions off and he feels he is being cross-examined. He says it is because of my job. I do interview and try to catch people in lies. Which is what I am doing with him. Yesterday, I asked my husband why I did not yet have a birthday gift (my birthday was three weeks ago). He had brought me a camera, but I am electronically challenged and as I told him a good gift for me is at Bed, Bath Beyond. I love cooking. I want a new cutting board. On Dec 9th, his bday came and I gave him a Droid2. It was buy one, get one free so I had one for mysel. I wasn't sure I would keep it though. It was hard for me to operate and I don't like the color of the phone. I like pink. He later bought me a pink cover for the phone. Over a week later, I asked about my bday gift. He said he took the things back, but had no time to go to BBB. I said if it was something for him, he would have had it by now. He disagreed. My Question: Are you saying that if you needed a special memory card for your Droid you would not have gone to get it when I gave you the phone? Answer: No, because on that day he was taking care of me (I was sick). Q: are you saying you would not have gotten it on the next day? A: no, because he has a memory card. Q: I am talking about something special, something you don't have here, something you have to go out and buy. A: probably not. Q: When did you get the pink cover?. Don't remember his response. More Q's and he says he did go to the cellphone store on Dec 9th. He just forgot about it. He went and had his license renewed and then went to the cellphone store. He went to the store to get my pink cover. While there he asked about things he could get for his new phone and bought a few things. Q: why go there for my gift when I want a cutting board ? A: he had no time to get to BBB. Q: why not just go to Target it is right next to the cellphone store? A: he didnt think to go there. Q: why no time to go to BBB? It is closer to dept. motor vehicles than the cellphone place. I don't remember his answer. I was tired, exasperated and angry by then. He hates me playing detective, but doesn't realize I hate having to do it to get to the truth. What do you think of this incident? What can we do?
I should add, my belief is the lies are to cover that he does not have the money to get my cutting board, because he spent it on himself and on his cigarettes.
It is my opinion that he takes care of himself first and if there is money left, I will get something. I have gone through numerous Christmas' with no gift.
