Hi Ahlags and welcome to the forum.
I’m so sorry to read your story and wanted to let you know that you are no alone. Everyone on this forum has been affected by alcohol or substance abuse in some way. Either their loved one, or there are some recovering addicts who share advice and support too.
I found myself wanting to vent when my son had relapsed. He takes alcohol and cocaine. The alcohol is a trigger for drugs, so really it should be avoided at all costs.
Read the other stories, “share your stories ” then click back to 15th September. There’s some good advice and support. The Forum home page is helpful and the Icarus Trust posts here also.
I wish I had all the answers for you, but your bf will have to admit he has a problem then attend/go online to the aa or ca meetings. He’ll be meeting others in the same situation and others who are years clean who offer help and support.
I hope and pray you both get the support you seek.
Take care of yourself
