i'm sorry to say this but I don't get how your offended. anyway, the fact that he quickly said oops after his mistake means it was obviously a typo. even if it was upsetting to you, lashing out like that was totally not called for. you should apologise and try to explain why you got upset... better then how you have here.
i honestly feel more sorry for your boyfriend than you at this point. don't lose your relationship over something like this.
