Lately, our relationship has been really strained. I currently live with him, but he's never at home. He's always working or out partying with his friends. My parents are divorced, so for him, that means bringing random girls to the house. As I am in the bedroom below him. I've tried to talk to him about it, but he just doesn't care. He tries to buy my brother and I off, like it's not a big deal. I wish I knew why he acted so immature. It would probably help me understand a lot, but I'll never know. His partying seems to be getting worse. He's almost forty years old as well. I just want him to realize that my brother and I are good children, and for him to stop treating us differently.

He probably just never wanted kids so he tryes and blocks you guys out and it sounds like he misses some one and is replacing the pain with drinking and sex

How old are you?
