Husbands acting distant

Jane
Anyone else's husband acting distant? Mine hasn't been giving me really any type of affection, all he says is my belly is getting bigger. It kinda hurts to hear him say that, he told me he doesn't want me to get super huge during pregnancy, but I can't really control it besides eating healthy. Also, he hasn't even been happy with the whole pregnancy anyways! This is something he wanted more than me even! Idk what to do. I'm an emotional wreck, ppl around me feel my husband is acting different too. Possible affair? He does work 3rd shift and this distant thing has been going on for 2 weeks now...
