Thought wrong

So our baby came five weeks early and we spent a week in the NICU and my husband constantly had to go outside and would be gone for hours mind you I had a c section and was left alone most of the week I was there glad I figured out how to manage by myself or with the help of the nurses. We have been home almost two weeks and I thought having the baby wouldsex bring us closer but honestly it's tearing us further apart he spends all his time in the garage tinkering around and we see him from 8pm until bedtime which isn't really bad as my baby needs to be fed every two hours. He says I don't ask to help because you tell me you don't need it and I said that's right I don't need help but just sitting on the couch watching a movie cuddling with us would be nice a few hours a day but I get nothing last night he left cuz we got into a fight and didn't come home until 9am he was gone 12 hours. I just don't know what to do I keep telling myself it'll get better but I don't think so.
