Selfish husbands

So anyone else feel like their husband is going through some weird childish psychological stage? Don't get me wrong, my husband is usually a wonderful man and a great provider. But lately, he has just not been excited or making the effort like he was when we first found out that I was pregnant. We just got in a big argument because he wouldn't agree to drop a chair off at the place where I am having my shower this Saturday (which is literally 5 minutes from our house). He had made comments like "well I'm just worried I won't be able to do what I want now". It's a little too late for that!!! Anyone else feel my pain??!
