This is troubling to me. It suggests that he acts like a different person when he drinks, which is an unsettling thing for a family member to have to deal with. Also, it makes me wonder whether he is not supportive of you when he is sober. I second the recommendation for AlAnon or AlaTeen, which can help you learn ways to approach your relationship with your father and learn healthy ways to react to what he says.
It sounds like drunken ramblings to me. Regardless, you’re getting a lot of mixed messages - he wants you to have a social life, but knows you have friends. He wants you to be “fixed,” but he knows you’re not broken. He wants you to party but doesn’t want you involved in what happens at a party.
My mom does this, and she does drink. Heavily and often. Only in my case, she’d tell me I was fat only to get upset when I didn’t have seconds for dinner. Or blubber all over me when I was 6 or 7, telling me her problems like I was her psychiatrist then proclaim how protective she was of me, shielding me of the trials and tribulations of everyday life. Now that I’m older, she’ll tell me that I’m too hard on my son, then in the same breath tell me I’m pampering him.
I really think you need to take what your dad is saying with a huge grain (or bucket) of salt. As noted upthread, every parent wants the best for their kids and it’s tough finding that line between the two extremes. It sounds like your dad means well, but he probably doesn’t realize that he’s sending you mixed messages or that he’s hurting your feelings. Whenever my mom drinks, she often forgets what she said while she’s been drinking and doesn’t realize that she’s telling me two different things. That doesn’t excuse the behavior, though.
