I think it must be normal I am 38 weeks and I feel like my husband wants nothing to do with me anymore. The other day I hid in my room and cried all day and he kept coming to ask what was wrong but I never told him because even at the time I knew it was probably just my hormones. But soon your babies will be here and your hormones will start to level out and life will be good :)
its totally normal especially towards the end im 37 weeks tomorrow and its exactly how I feel. but once the babys are here it wont even matter. 3 more weeks!!
Everyone has a different pregnancy experience, so dont compare to others.. Especially those on tv or in the media. Given that your due date is nearing, maybe your husband is coping with the stress and anxiety by withdrawing..? He probably just feels a huge responsibility and is mentally preparing himself (though you'd likely benefit from him communicating that). You will be awesome and it will alllll work out you're so close!
