My EXDH is a functioning alcoholic. We separated 10 years ago and have 2 DSs aged 18 and 16.
Following our split he declined pretty quickly, which I didn't attribute too much to alcohol but looking back it's been at the root of most issues for at least the last 20 years.
When my youngest was 11 he stopped going to stay with his DF. This was due to witnessing my EXDHs girlfriend trying to commit suicide, his DFs drinking and anger, and the general chaos of the house. My oldest continued to have contact, mainly as he was a little older and seemed more oblivious to what was going on. It was a really difficult time.
So now we are here. My 18 YO has started to open up more about his DFs alcohol use. His DF has confided in him that he has stage 2 liver disease and high blood pressure. Said hes now moved away from wine and is now drinking vodka as he says its reducing his intake. I see this as an escalation.
He has also started to withdraw socially. Previous to this he would occasionally watch DS play his sport and meet once a week with friends. He has stopped doing this now.
I also saw him a month or so ago. Despite him being in his garden I thought it was a stranger. Hes extremely bloated - possibly weighing 3 stone more than I he was when I saw him 6 months previous.
I've spoken to my DS this afternoon and we have discussed this at length. I expressed my concern for his DF and also for him and his brother. My DS has asked him numerous times to stop drinking. My EX tells him he has a grip on it.
DS has said he is going over to speak with his DF this week. Armed with information on how he can get support. He said he's going to be assertive and speak to him as an adult male rather than the father/child relationship. Hes going to tell him explicitly just how concerned he is for him and his siblings (there is another child who is 7). He feels that he needs to try this because if he doesn't he will regret it.
EXDH has a DSIS that lives abroad, no parents and his DP has more of an issue with alcohol than he does (according to DS).
Due to the issues with my youngest and other things my EX cannot bear to engage so there is nothing I can do to support him, despite wanting to.
Whilst he was an awful DH and has been a pretty awful DF, how can I support my DSs through this?
