Husband still not home.. and made me feel like I’m in the wrong

My husband came home after work for maybe 5 min… then he said he was going to his friends for just a bit to work on our camper and then he’d be back. He NEVER just stays just a bit and I’ve talked to him about it. How I feel so disrespected especially now that we have a 5 week old and a 2 yr old.

We ended up going to the park while my husband was gone, but our son’s shoes were in his truck. So I stopped by and grabbed those.. went to the park and our son started asking for daddy plus it was starting to storm so we left, got ice cream and then I went to see my husband again to see where he was at with things and when he was coming home. Plus I was going to drop our toddler off so he could see his dad. My husband was drunkkkk. So I got pissed and left, said eff it and had to calm down our toddler who was screaming and crying for daddy. All while also trying to keep our newborn asleep because he won’t let me put him down & he hasn’t been sleeping. It then turned into 11pm and my husbands still not home, I’ve managed to make dinner for us, all while trying to pump, hold newborn, feed us etc. so I drove back over there again. I should have handled it better but I was pissed off. So I’m like when do you plan on coming home?? I need help, our son misses you and keeps crying for his daddy.. all he kept saying was In a bit. So I left.. but I definitely caused a scene in front of his friend.

My husband does this shit ALL THE TIME and just leaves me. Early in the mornings, afternoons… it’s 1:30 am and he’s STILL not home. Am I in the wrong? I’m running on barely 4 hours of sleep because he doesn’t help at all with the baby and I don’t get naps. I just want to be important enough to want us as a family. He said he had a shit week and he just needed to cool off from it. Even though he’s been at this friends house at least 3 times this week doing the same shit. “Cooling off and drinking”.
