How old are you and what gender are you?
It doesn't sound like your father is abusive to you in any way from what you have shared with us. I don't see why you're so bent over it. I'm sure he just feels uncomfortable expressing his feelings towards you. When he's drunk his inhibitions are lowered, he opens up. I'm sure when you're not around and he's discussing you with other people, he speaks favorably about you. The only time I have really good conversations with my pops is when we are talking about a subject we can both relate to and are interested in, which is pretty damn rare. I'm sure when he speaks "negatively" towards you, he's only trying to wisen you up and make you a better person. If you're fucking up, what do you expect him to say?
Hey, I noticed you got a D on your report card. I know you can do better than that. You just have to try harder next time.
Well that was an unexpected trip to the police station in the middle of the night. Hopefully you've learned your lesson. I know you're smart enough to avoid another situation like this in future. Let's go grab some breakfast at Denny's, my treat.
If I heard shit like that growing up, I'd be dating my cellmate right now and punking the fish out of their care packages and toothbrushes. I think more people would respond better to some sort of punishment, some verbal lashing, and maybe a good smack in the chops. Needless to say, I don't come from a "go take a timeout" family. A little tough love can go a long way and help you build some character and a backbone. Sure our parents came from a different time, when things were different. As each generation reproduces, I can't help but think we are breeding a softer, pussified, crybaby society. It grows softer with each new generation. Maybe a big war or a nasty recession is just what we need to help curve this epidemic sweeping the civilized world, in a twisted sort of way.
Now if he beats the shit out of you for no reason or touches your butthole or something, well that would be a totally different story.
I was assuming you are a male, so if you are a female or an effeminate gay man, than you should disregard a lot of what I said.
