My husband is bad influenced by his mother if we can call that that in My life

His mood is a perpetual roller coaster: happy and then sad mad jealous. Las Christmas only my little one got gifts and he got mad nervous that my little one told me it was as if a tsunami cane and destroyed our house or a comet. Not fun.
His father has no patience at all even with his grandson. He asked twice something about a new game and he told him wait your dad will explain and the tone was mean and rude. My husband coward said not a word. We are with 3 ill mad sick people. They have serious mental health problems. I told my husband to go see a psychiatrist or psychologist and he said no of course. He told me to go instead. He tells bad things about me to our friends to feel better about himself. He has no self confidence no courage nothing and he needs to put me down to feel better. He barely makes me compliments. If he does it is ironic like I have white hair but I still have more hair than himself. All the world has to turn around himself. He never tells me things as I have to discover them when he talks with his friends about it. My little one and me went to Vietnam for a special reason: my niece was about to be born, I wanted to meet her and my sister-in-law and see my brother and mother. He found all the excuses not to go. He did not answer me when I told him to book his flight ticket to come with us. The prices were going up every day. He lied to me about a conference in Vietnam he could go to and we could stay more there. But the next day he got mad for no reason and decided not to go anymore. Maybe he lied to me to make me confused or he did not get it. Maybe he did not get it as his boss went to a conference in Vietnam in September. He is playing unfair at work too. He thinks he is smart and can manipulate anyone. He is a liar and can do anything to feel good about him. He can be nice then a nasty person. This is the second time he invites his parents without my approval and then the old mother is not happy as I am ignoring her. She can be happy I am not calling 911 to make her leave. I do not say a word for my little one as he needs to have a normal life as much as possible. At least he goes to school where all is nice and positive great for his soul and well being. The weekends are harder because I have to stay with all the 3 creasy. They organize when we eat what we eat where we go. At least not this Saturday we go to a party at the park and to the beach at a restaurant. Sunday no idea. Thank goodness days are going fast ! I have things to do, errands to run, etc. I keep busy out of the house. This house does not feel like mine anymore it is a pigsty and a retirement home for dead people with no heart. They are not invited by me, not discreet they talk loud are noisy people. My husband drinks a lot with his father: beer, wine and stronger alcohol. I do not drink with them and I go to bed early as I do not want to talk to them alone are they are mean. They already criticize me each and every evening and my husband is listening like a stupid immature childish child. He does not want to say no or stop to them as he is coward and wants his peace.
