Idk what to do or feel

Saturday we went out to the springs and had a great time, then came the evening, and he wanted to go to the bar for a shot that night for his birthday Sunday. We had our youngest with us, so I said to have one shot and come back home that it was fine. I don’t tell him he can’t do something. Then two hours later he decided to finally come home, but not inside. He stays outside with his friends while I’m inside with our daughter who just threw up and sick. So I text him and tell him she sick and I don’t understand why he’d rather be outside partying with his friends then being a father and coming inside and helping me with our sick daughter. He text me back wow. So I fall asleep with her and around 2:00-2:30 I wake up to find him gone. No where to be found. Then our daughter wakes up and I go looking for him. Come to find out he left with his friends on the boat and didn’t bother to tell me or care. It was a big argument when he got home. That he should be allowed to do whatever he wants that he was just out on the boat with his guy friends and I shouldn’t have a problem with it and should be okay with it. In tried calling so many times. He supposedly lost his phone in the boat but it was on when he got back home.
