Boyfriend not coming home 2 nights

Ok, so my bf and I had a bad relationship in the pass but we talked and try to make it work.

Yesterday it was snowing so bad so I told him to stay at his moms ( she lives closer to his work) and he did, he has a past of drinking to much with his brother so today he seemed to be active on fb all day so I asked him if he went to work and he said “yeah” he dint txt me or call me (my phone is broken but I could txt him on messenger) he only send me that his battery was at 4%, today he hasn’t called or txt and it looks he is going to spend the night there cause it’s already 12 am.

I’m thinking he didn’t go to work and he stayed there drinking with his brother he has done that in the past) what would you do? He is not an alcoholic but when he drinks he drinks a lot and that’s when the big fights happen. What would you do. I’m so mad mostly for the disrespect and not letting me know anything, I know he has access to a charger at his moms. I feel so stupid talking about this here but I’m so lonely.

We have a one year old, and when he was born he did the same thing but he change but it looks like he itsdoing it again help.

Day 3 he hasn’t call or txt me yet I’m so overwhelmed and having major anxiety attacks I feel so lonely and want to leave him but I can’t support my son and me. He hasn’t even call to ask about our son? Am I really exaggerating please help.
