My dad fell off the face of the earth again, which can only mean one thing. He is back to drinking again. All my life I have gone through this with him. He gets sober for 90 or 120 days and then he gets out of rehab and he starts drinking like 2 or 3 weeks afterwards. I am just so done with it. He doesn't seen how it affects my little sister and I. It kills my little sister more because it is her biological dad. He is my adoptive dad but he raised me so he is my dad. How do I tell him get sober or I am done with him for good. Last time he got sober my ex-fiance and I drove him all the way to Ohio from Indiana to a half-way house to make sure he stayed sober. What a lot of good that did he got kicked out of there for drinking. He then checked himself into rehab. He went through it and got out and went to another half-way house. Same story he got kicked out of there for drinking. He was on the streets for a little while. My ex-fiance and I told him he could come live with us but we had a rule he was not allowed to drink. My ex even agreed to keep no booze in the house so he wouldn't be tempted. It never does any good. He has no job but still finds a way to get beer. He finds friends who drink and they will buy him beer. He will sell his stuff to get beer. When he does get a job he loses it because of his drinking. He gets so drunk that he passes out and misses work often. I love my dad but I can't deal anymore. He gets violent when he drinks. His drinking and violent behavior has caused me to have PTSD from the things he did to my mom when I was a child. He complete denis doing the things he did to my mom but when I was 4 I could not make up the things I saw. I have told doctor after doctor about what I saw and my story has never changed. That's what led to my diagnoses of PTSD. I am sorry I took so long to tell this story please help me. I want him to get sober for good but if he doesn't I am fully prepared to kick him out of my life for good.
