Distant husband relationship

I had a high risk pregnancy with my son he came a month early via emergency c section, I had gestational diabetes. A lot went on I was in the hospital for a while.

My husband returned back to work and we had our first  argument yesterday I think for both of us it’s been a lot mentally and physically.

Me personally I’m recovering from my first c section which is different than my first child who I had regular vag

Mentally I feel fine honestly

My husband on the other hand is always tired and goes to work comes homes and is distant doesn’t seem present I’m not to worried about it but it bothered yesterday when I asked him for help with something and he told me no I was so shocked and quickly got upset. Any one else feel distant between there significant other or husband ? I know this will pass and we will be ok but I miss the love connection between us.
