Am I asking too much of my partner or is he just not doing enough?

My partner, who is also my son’s father, goes out often. He has always been this way. Has a very active social life, an organization that he runs with his friends and they host many events, he’s an avid poker player and goes to tournaments plus works a full time job and he also runs another business on the side. After having a child though, you’d think he would scale back a bit, but lately he just seems to be out more. We have been arguing a lot about it. I just feel left behind. I also work but I obviously have scaled back on doing certain things to make up for time with my son. My partner hasn’t. So a lot of the time, I’m home alone on weekends with the baby while he’s out playing poker, etc. I’ve voiced my concerns to him and told him that after having a child, priorities change. He has called me boring for this. Also says I’m delusional whenever I say he is barely home. He has a brother whose wife and children (all 8 of them I think I’ve lost count) live in the south but his brother travels a lot. Also plays poker, does music, & I don't know what else to be honest but he’s usually up north where we are while she is with the kids. I don't know if he thinks that’s the life I want I’ve told him no numerous times that I’m not ending up staying home raising all the kids alone while he’s out. I don't know I guess I just need advice. Am I wrong for being annoyed? Am I truly delusional? Am I asking for too much?
