Husband pushed me

I had an argument with my husband (although it should’ve been just a calm talk). I went to him in bed and hugged him and thanked him for being a good dad and helping me around the house but I had one thing to ask him to do to help me out more. I asked him to take our dog out while I’m getting our 10 month old to bed every night. He answered with “I can sometimes”. I questioned what that meant and he wouldn’t elaborate on what “sometimes” means - he would just keep repeating “sometimes”. I kept questioning him and he kinda shoved me off his chest (I was laying there when I asked). He started to get mad that I kept asking him what that meant. So I was sitting on the side of the bed not touching him because he had already pushed me off his chest and he sat up and pushed me off the bed and got up off the bed on the side I was on. (I had to stand up from the force or I would’ve fallen- i wasn’t hurt or anything but it shocked me). Mind you, the entire other side was available for him to get up and leave through.

I obviously walked away telling him fuck you (I’ve never said that to him before) and then text him telling him he better not ever lay his hands on me out of anger again.

He was blaming me at first saying I’m relentless and wouldn’t end the conversation.. but now he’s realized that he needs to work on his anger and he was taking his own stress out on me. But another issue is that he’s OCD so he is on his computer and phone A TON and I tell him all the time his son and I need more attention. Ever since this fight he’s been super distant and watching videos on his computer/phone- but whenever I bring up that he’s ignoring me and I’m sinking into a depression from thinking about our relationship, he tells me he’s working on himself so he’s quieter right now? It’s been about 2 weeks since that night.

For reference he’s got a prestigious job that took a lot of hard work to get into so he’s not some bum or anything.

Anyways - I don’t know what to feel or think.

Edit: this is the first time he put his hands on me, but he does get angry easily and will raise his voice at me when I calmly communicate my feelings etc. because he gets super defensive. And no I don’t nag, I asked in the nicest way possible. I simply want to communicate properly, which means I’m allowed to ask him what his vague answer meant.
