He is punishing "you" for his own insecurities Seeyalater. He has "no right" to come home from work angry and demand sex from you. He "tricked" you into signing away your rights to that house, he did not like it when you found out about that either. He also wants nice things and a bank account but he doesn't like "working for these things". He doesn't really want to give "you" anything. He accuses "you" of not being satisfied with a smaller modest home, in reality it was something "he" did not want, after all he did make sure you signed off on any ownership, he prefers to be grandious.

He is ashamed of his own feelings, doesn't like you to see or hear them either. He has been told to "man up" and it could be that his father was/is narcissistic. He reacts to you with blame and anger, also reacts to others that way too. Getting help means having to share his feelings, he considers that "weak" so he refuses to see anyone. He obviously doesn't know how to deal with people, hense he is very unhappy at work too.
He works out obsessively, he needs to look in the mirror and be pleased with himself.

There are a lot of red flags that you already are finding out mean "trouble" for you. As I mentioned, after you finish school have a list to discuss the "facts" of what you are experiencing with a therapist.

You never answer the question of if he may be taking steriods either. Well, that is also very important.
