Husband does not understand my pregnancy!!

Anyone else feel like instead of getting closer the pregnancy is pulling them apart?! I am 9 weeks now and I am moody, yes I understand that I have a short temper and I snap but I just feel like my husband doesn't understand me. He actually told me today that he believes cravings are an old wives tale, that my pregnancy can't be used as an excuse. Which I don't do, everyone else tells him constantly that all these symptoms are pregnancy related and up until today I actually thought he felt the same way. It's so hard because I already feel so different and have to come to terms with all these symptoms on my own, to still have to add on feeling alone because he doesn't connect with me. Any suggestions as to what he should read or what I should tell him so we can connect and be excited for this together?!!
