His words and actions are contradicting - What does he really mean?

In a really short way to put it, he's stubborn and proud, and there's a certain "do as I say, not as I do" element here.

Thing is though, I don't think he thinks twice before he says something when he gets mad. It's like when he gets mad, his adrenaline gets going a little bit, and he says something really quick in spite of the fact of whatever made his adrenaline get going. It's like when an athlete says something in a press conference right after a bad loss, that he retracts after he realizes what he said. It happens a lot. And I think in situations when we get mad is most likely when contradiction stuff is to be said. And I'm definitely guilty of getting mad and saying something I didn't mean at the time I said it. I think we all go through that at some point in time. I would talk to him and try to get him to see things from your perspective and see if he changes his way of thinking.

I would personally just forget about him, since it seems that he get's mad at just about everything, and contradicts everything you do and say. He seems controlling which I dislike a lot.

I think he's not worth it if he treats you that way, but that's just my opinion. Hopefully everything goes well.
