Am I wrong?

My fathers child is a narcissist. I thought he would change once the baby got her but he only became worse. He left us 2 days after we were home to go smoke with friends. Our child is 5 months now and I’m the one constantly reaching out to him. Our baby enjoys him. I would love for them to have a bong but his lifestyle is just not healthy. We don’t live together and we are not together. He’s not helping me one bit with parenting. He likes to parade our daughter around and post pictures that I take of her like he was with her. I’m getting sick of it. Today he went out to a bar and got high and who knows what else. I sent him a message telling him to get it together. I didn’t use profanity or any type of name calling. I am just so frustrated. I don’t have any help. I blocked him on everything. He literally chooses smoking and parties over being with his daughter or helping me. I know I can do it on my own but sometimes I would just like an hour to myself. Am I wrong for cutting him off completely? He’s 34 and has no ambition or goals. His family encourages his behavior as well.
