AITAH for being upset with my eldest son?

I only need parents point of view on this because they are the only ones who understand me at this point.

I haven't always been the best father and I regret that every day. I had my eldest son, Nick, (M23) when my ex and I were 15. We both didn't have good relationship with our parents and that unfortunately meant that we both turned to alcohol and drugs.

And as much it breaks my heart, we would often neglect Nick. That meant that Nick would be left to "raise" his younger siblings and had to pick up the slack.

I'm not defending my less than stellar behavior but I was a wreck after my break up with my ex. I was drinking everyday and night. I could barely function.

But a few months ago I've picked my act. I've been sober for nearly 11 months, lost 67 pounds, got a better job and finally got my high school diploma.

Today was my birthday and marked the date for 11 months of sobriety, and before when I first got sober Nick would do something but today it was nothing. No breakfast, no banner, no balloons. Not even the kids where there.

I asked Nick where were the kids he dryly told " Cole (M16) is skateboarding with a friend, the twins (M13) are at the park and I dropped the triplets (2F 1M 13) at the movies to watch Deadpool"

I simply asked "why are you doing this?" He again said dryly "do what? They had plans and I can't force them to stay here. "

This is probably the part where I am the asshole. We went back and forth for a little bit and that's when I said out of anger "you can be exactly like your mother"

He just sighed and stormed out. He still isn't home, and it's been a few hours. There is no dinner, no laundry done, the kids bags aren't packed for school. I called but no answer.

So what should I do Reddit? Should I apologize? What should I say to him? How can I fix this?

I'm sorry if this isn't very clear. This is very rushed. I'll answer any questions
