Boyfriend angry at my lack of sex drive

I'm 8 months pregnant and my boyfriend doesn't understand that sex makes me gag right now. We haven't had sex in 2 weeks and he is acting like he is dying. He wants me to give him at least blowjobs/or handjobs and doesn't understand I'm just physically exhausted/half sleep when he comes home (he works nights). He has made me feel real guilty about this-saying he feels neglected and that I don't want him sexually anymore. Am I in the wrong or is he being unreasonable? I honestly don't care if he watches porn at this point-I don't want to be touched!!!
