Offended.

Every time after my boyfriend and I have sex lately, he picks up my BC pills and just stares at them making sure I've taken my pill. (I've NEVER missed a pill) my point is that I find it to be an invasion of privacy and sort of offensive that he doesn't trust me. We've been together for almost two years. I told him it was offensive to me and he basically said he doesn't care and he's not going to change. Should I be offended or bothered or am I just being overly sensitive?
