Mean persons in My life

My husband is mean and his parents are bad. He is nice with his parents now and mean with me. Again. He has a conference in Sydney and wanted to take us but now not anymore of course. I do not really care. He thinks he is smart.
I told my husband I wanted to take my little one to the beach. I sent him an sms no answer and then when we come back after a nice day, it is a problem as always he is influenced by his mean parents or he is mean himself? Mentally ill? He is messing with me and Benjamin all the time.
I know they are criticizing me and I do not really care at all. I have a tick skin and I do not care. He is mentally unstable and he must have a mental illness for sure and be maleficent. He tells me I am not raising nicely my boy as he is unpolite, etc. But he is the father and he does not like this answer at all. Because it is true. Of course. He is so wrong of course. Life is again full of surprises for me. In a good and bad way. He shows me his true face and it is a bad guy. A marriage gives me rights and normally respect as his wife but no. Not with him as he has big problems.
The in-laws came to destroy me and my marriage and I really do not care as I am still alive and have a thick skin for sure. I am concerned about my little one. A separation or divorce will be tough on him as he loves his dad he never sees and has no patience with him. My husband goes late to bed as he works, plays video games and watches tv or something else by himself and then he goes late to work at 11 am or noon. The weekends the same he sleeps in. He does not want to do much with my little one and I. We skype almost every Sunday with his parents and they have nothing to tell and it is close to noon. Sunday is a family day but it starts at 1-2 pm with him, which is annoying and makes no sense. He is selfish self centered.
After seeing a lawyer he will change his attitude towards me as he is not generous at all. He is generous with his friends to show off but he cannot do that as he wishes with his small income. I am staying at homes and taking care of my son, the house and other things and he does not care as it is all about money. Never a thank you from him for the meals I cook, he just criticized my little one was raised. Never a good word for me and not so much for his son. He must be narcissistic very ill. I am not a psychiatrist but I am sure he has big problems. I hope I am not the bad guy here as he is ill and I am not. I am too nice too patient with him and there are my flaws. I am trying to protect my little one from this mess.
Please pray for me and my little one as we need to escape from this messed up situation. His father is crazy and his parents are crazy and evil. Dear God please help me! Thank you!
