My husband don’t help out with the baby

Hey you guys. My husband has really changed on me. I never thought he would be like this. When I was pregnant, he was so happy and singing to the baby. But once I had him, something changed with him. He doesn’t no help with out. Is it normal for a man to not help out with the kids but only wanna play with them. Ok this is why. So I noticed that with my son, I left the hospital and discharged to my parents because I had a c section and my husband work 12 hour so he can’t be home with me. Alright. After i healed from recovery around 2 weeks and I went home. So my first night back home with 2 weeks into recovery from my c section, I got up for the baby. Then I noticed I been getting up the last few weeks feeding the baby that I bottle feed and change. I would wake him up and tell him the baby is crying. This man, that I couldn’t believe was my husband told “let me sleep! I gotta go to work! You handle it”. I was so pissed off. Like I understand you gotta work but dude, help me out! I’m going back to work soon too! So after 3 months; he still wouldn’t get his ass up. I get up. But yet he wanna play with his son. The man don’t even help me bathe him. I even tried to be petty and when the baby woke up, I put the baby right in front of him. He got so mad and pick up our son and brought him back to me and said “I gotta sleep in order to work. If I don’t work, how is bills gonna be paid. I pay mostly everything around here. Y’all depend on me”. I don’t pay many bills because I am in school trying to finish. 😓 I was like wow. But this is your kid too? We argued a lot about this. This is a big problem. He making me feel like a single mom that received child support or something. A year later, our son is 1. Now he tell me that he can handle him when he get a little older and he need his mama and need to be around me. Oh yea, so I’m pregnant again and I’m getting very paranoid about the new baby. I don’t wanna repeat of this. So my question is.. I know this is dumb. But is this how a father is supposed to be? What can I do? Why is this man just wanting to play and not actually put in work bathing feeding or assisting with changing? Where is the man I knew?
