Stop drinking....it is only a bike, your Dad is OK which is what is most important, and yes if it is in his name, then it is technically his IMHO. Quit acting like a big baby and get over it, you won't get any sympathy here. Sounds like you and your Dad need to have a heart to heart AND YOUR WIFE as well. Yes people can suck, yes that is life, yes you need to handle it better. Set a good example for your kids, stop acting like a fuckstick.
