6 Situations When the "Real You" Emerges

I need help/advice:

My boyfriend came home after a long day, and I went to his house to takehim dinner. He is tired and has had too much to drink while at a meeting. I am going outside to the barn anyway, and he asks if I will feed his horse and dog while I am outside. I say "sure". He gets mad and tells me I am f**king stupid if I would actually feed his animals for him when he is right there. And even more stupid if I would actually think that he would want me to feed his animals for him so that he can go to bed. When he gets upset something about me is always stupid... my logic, my thoughts, my feelings, my conversation.

He has told me that if I talk to his "ex" (he wasn't ever married, had a daugther withhis "ex"when she got pregnant on their first date/time, and he HATES this woman) that our relationship will be over. She contacts me and invites me to do stuff and I tell her "no thank you". He gets so angry that I don't just ignore her totally. That seems so rude to me and that's not who I am. I don't see the harm in a polite reply to say no. His anger and hatred towards her almost broke us up this past weekend. Should I be concerened?

And he drives while drinking beer with his 12 yr old daughter in the car. He takes his showers with his bedroom and bathroom doors open while she is in the house and even when she has friends over. He walks from the bathroom to the bedroom w/o clothes on and if the daugther were to walk around the corner she would see everything. I have tried to tell him to close the doors and he tells me that it's no big deal, she's a kid, and doesn't have a perverted mind like I do. I almost think he wants her to see him.

I am so confused. I have been seperated/divorced for almost 7 years and this is the first man I have really dated and had any sort of boyfriend relationship with. He can be so kind and thoughtful, and then mean and hateful. And I am wondering if his lack of respect for the laws and modesty/privacy when his daughter is around is indicative of something deeper? I wish they had a situation about this in the article.... if he is angry and mean when he's been drinking, is that the real him?

Thanks.. any help is appreciated.
