Should I feel offended and ask more or just leave it?

My boyfriend came to mine the other day and forgot to bring his f**s,so he went aday with out smoking,which I was proud of,so today I rang him and we spoke about things and I said to him,I'm proud of you not having some f**s the other day etc and he said don't be offended but I don't NEED a F** all the time,just sometimes when I'm BORED I have one =o well he goes outsides for f**s when we are out at pubs and when he is with me.I'm not a boring person and he has said loads to me that I'm not boring but now I'm paranoid that I'm boring him.

Do smokers do that or is he basically admiting that he is bored when he is with me?
