I'm thinking your Dad might be remorseful when he sobers up and remembers.
He might not even remember.
I know now that I don't drink, I often forget or don't realise how much others have consumed and what they may say or do is a result of that.
Thats despite me being convinced after every drink I had that I had upset someone or said something bad.
Its not nice behaviour.
You are right to feel upset and hurt.
Take it day by day and you will come to an understanding about how you need to handle his behaviour and tackle it.
I wish you the best xx
