I have no idea why everybody here is defending your husband for being such a cockbag.

The people defending him are also assholes- people like that stick together rather than address the fact that they should be ashamed of their behavior.

The whole thing seems obvious to me. Notice how there aren't any of those "my relationship is usually great, but...." "he's a great guy, but sometimes he's like this...." Look at how busy she is. The way OP says, "let me serve him a beautiful meal"; she waits on this asshole hand and foot. No one can come before him, not even his son. Husband is the manipulative, spoiled brat. Husband has always been able to do whatever he wants, all the time, by any means necessary. OP has stopped questioning him. OP has become a doormat. OP stays because she's been broken down and is now only concerned with the welfare of her son...right now that is the financial security, but she now realizes she may have to choose between that and her son being verbally abused his whole life.

OP is fine with not being as important as him in the relationship, her will has begun to break, but she cares about her son more than anything. She doesn't want it to start happening to him; she finally speaks up in her quiet and calm way. Sure, he starts small with brat, but he even admits it will get worse. He shows his true colors by threatening to leave over something so small- he loves himself more than anyone else. If everything in his life isn't absolutely the way he wants it, he's gonna nope out. Have to make sacrifices in life, compromises in a relationship. Otherwise one party gets shafted, and right now that's OP, soon it's her son, too, if she doesn't leave.

Make the choice, OP, would you rather be financially secure or have your son grow up being emotionally abused?
