My husband is nuts and mean in My life

After his mother insulting me, my husband took them for 3 days to nice places. I take my little one to a nice place for the whole day today and my husband tells me bad things like I am selfish because that day was supposed to be a party for his father because he built a cabin out of wood for my little one. It is nice but they were mean with me and the mother insulted me and did not apologize. My husband wants a divorce and tells me he is gonna see a lawyer tomorrow so nice guy. His parents told him bad things against me and they came to my place and treated me like shit in my own home. I did not kick them out after the insult for my little one and now my husband says I am the bad person. He told me the house will be sold. Just mean things. Coward.
I have rights in this country as his wife and the mother of his child. I brought the money for the down payment. He forgets about that. I should see an attorney myself and he will see.
I know someone who wanted to divorce his wife but did not do it because the lawyer told him the money he needed to share with her and the son. So they stayed together.
She stayed for what she promised the day of her wedding and he wanted to keep his money.
At least the uninvited in-laws are leaving on Tuesday! A good thing. My house is a pigsty. Now the in-laws are meddling in about what I do with Benjamin as they are mean.
If you have advice it would be greatly appreciated. Thank you!
This guy my husband is mean always putting me down for no reason. He is working but dies not get a big income. Without my inheritance we could not have afforded this house and he us not happy.
