Moms when did your SO start bonding

My baby girl is 6 weeks old and my boyfriend still doesn’t have a connection with her. He doesn’t want to hold, talk, change, or feed her. I feel like I’m parenting alone. He never gets up during the night, never willingly holds her unless I place her in his arms and doesn’t talk or try to interact with her. He just puts her binky in her mouth and sets her on the bed next to him. I feel so alone and I feel like he’s not being a good parent. I need a break some times and he yelled for me when I got in the shower it was literally 5 minutes. He comes from work and drinks a couple beers and watches tv then goes to bed. How do I get him to want to parent I feel so alone like I made a bad decision having his kids
