Dead beat father

I’m trying to move on, my spouse is a dead beat dad & I can’t seem to process that & just move on. Our newborn is a week & 2 days old, my ex has not made the effort to see him since he was born. He’d tell me “I might come see the boys today” (we have 2) I tell him okay, can’t wait for you to meet our boy. He’s said this 3 times. He’s bailed or never showed each time. It honestly breaks my heart that he makes 0 effort to see our babies. He wanted our second born as much as I did when we were together, at least I thought so.

He was supposed to be there for the birth, didn’t show. I had my mom with me instead. I’m only 22, and he “left me” with 2 babies to watch on my own. Don’t get me wrong, I love them so much. Honestly wouldn’t trade them for the world. It just sucks how he won’t be involved in their lives. He can’t say I’m keeping them away, I’ve been waiting & asking for him to come see our babies he just never does. I blocked him today, after waiting a week for him to meet our baby. 😕 honestly sucks. He also chooses his alcohol over them/us. We’ve been split for a month due to his alcoholism & drug use. He says he wants to sober up, I try & support him & be there but he honestly doesn’t make the effort to be/stay sober. I understand addiction is hard, it’s been 4 years I was with him. He was good for the first 2 years, these last 2 years have been rocky.
