My dad, 67, moved in with me about 3 years ago following a divorce. Initially things were ok, he retired from full time work last year and I bought my first house shortly after and we moved home, he came with me. Since we've moved, he has become incredibly dependant on alcohol, mainly whiskey, he can drink an entire bottle over 2 evenings. I've been in a relationship for about 9 months now and my partner moved in with us this year, they get on well. At Christmas my partner proposed to me, he asked my dad prior to asking me, as he felt this was the respectful thing to do. When he asked my dad my dad's reply was "as long as you know what you're getting yourself into". Neither myself nor my fiancé know what he meant by this comment. After speaking to my dad, he proposed. We then went out to our local pub, my dad was already there. When I showed my dad the ring, he didn't congratulate me, show any emotion, instead, he said "well he could of f***ing asked me first". This was in front of our friends, he then got up and walked away from the table where we were sitting. Before Xmas I asked him to not get drunk as it was out first Xmas in the new house. He didn't listen, he went out on Xmas eve, didn't get home until gone 1am. My fiancé woke in the morning to find food all over the kitchen floor and the front door wide open, please bare in mind this was Xmas eve so the house was full of presents etc. We woke him Xmas day morning for the usual present opening etc, all he kept saying was "come on, hurry up, I want to go to the pub". He then left and did exactly that, once he had opened his presents. He knew I was cooking dinner, he wasn't home in time so I ended up having to call him 3 times, he eventually came home, completely drunk. He sat at the table slurring his words, his face practically in his plate of food. As soon as he had finished he went upstairs, was sick and went to bed. His drinking is out of control, he has had 2 bad falls, the first, he smashed his head on the worktop as he fell. The 2nd was only last week, he fell coming out of the pub and did serious damage to his left leg, this resulted in me having to take him to A&E the following morning. Myself and my fiancé confronted him and asked him if he was unhappy or depressed and that's why he was drinking so much. He said no, he admitted that he may have a problem. He also said that he was going to stay away from the whiskey. 4 days later he bought another bottle of whiskey, I confronted him and said he'd said he was staying away from it. His excuse was it was just for a nightcap, the following evening he drank over half the bottle over 2 hours. I've just recently found out that I am expecting my first baby, which obviously myself and my fiancé are over the moon about. My dad doesn't know yet and I'm petrified to tell him. I've seen such a mean horrible side to him over the last year, the mood swings are constant, he can go for hours just not talking and ignoring people. As you can imagine this doesn't make for a nice living environment. When he retired he gave me some money towards my deposit on the house, it's almost as though he now sees it as it's his home, he even told our friends in the pub that it was his house. I don't ask him to contribute towards bills etc, he just pays for a little food shopping now and then. He works 2 nights a week at the moment also. He's just making me so miserable, I'm dreading telling him that I'm pregnant as I know he won't have anything nice to say about it. I don't want to have to ask him to move out as I know he wouldn't manage and he wouldn't be able to afford it. I'm sorry to go on and on, what I've explained is only the tip of the iceberg, things are, and have been bad for some time now and I'm at a loss as to what to do. We've tried talking to him but to no avail. Obviously, now, the last thing I want or need to put myself under this much stress now I know I have a baby to think about.
