He's an alcoholic arsehole!
I'm not gonna bother with all the bullshit - just get rid!
I'm the child of an alcoholic and toxic home like yours sounds it is and quite honestly I will say if you stay you're letting your child down.
He didn't "use to@" have problems with alcohol he's a belligerent and useless drunk! You're far better off without him!
You had a 3 hour nap after a pretty much sleepless night (at least partly his fault!) he did sod all aside from drink, moan, and languish in his pit most of the day!
Totally unacceptable when there's a baby in the house!
he absolutely has issues with alcohol and has previously admitted to being a functional alcoholic
This is quite a turnaround from your earlier comments!
And he's not functioning as a partner and father is he! He's not even present!
how much of his moods are my "fault"
Zero - the only person responsible for his "moods" are him!
Addicts lie and they NEVER take responsibility
Seriously - leave asap!
