Husband has no intuition with our 5 month old

Jessica • Happily married to my best friend and welcomed our first baby in July 2014!
We are first time parents and so the last few months have been super stressful for both of us. My husband helps out a lot, which I am very thankful for, but if I want to sleep in or go to the salon or even go to the grocery store it seems like he has no clue how to take care of our son! It's like he doesn't know how to read his cues. I lost my job while on maternity leave and while being a SAHM for the moment has been nice, sometimes I need a break too. I can't even take a shower without hubby wanting to know when I'll be done because baby is crying and he doesn't know what to do. Hubby has been able to go hang out with friends without me bothering him, he gets to even shower and go to the bathroom in peace, but when I want to do those things I am constantly asked when are you going to be done or when are you going to be home. I am extremely stressed out and short tempered because hubby gets his time but I can never have my time. I don't know what to do.
