Wow, thank you so much for all of your responses, it really means alot. I will definitely have a look and read through other threads. I clearly suffer from deeper issues regarding my childhood. I suppose what's really hard to accept is the fact he seems so fine now without me.. example..booking holidays,tinder and going to concerts, I feel like I did so much to help him yet he seems so fine without me, it makes me feel like I was his reason for drinking. Will he actually ever realise what he's lost!?
Iv grew up with drink around me Inc my mum, dad and sister, they all love to drink so I obviously accepted this was normal until I realised it wasn't.
