Struggling with in laws?

For context- my husband (let's call him C) and I have been married for 4 months. Before I met C, my parents sold everything they had to buy me a piece of land to build a house. The initial idea was for me and my parents to live there, but after I married C, my parents stepped out and said it's fine for C and I to live there.

Although parents already paid for 70% of the complete cost of the house, the house is under my name (so legally mine and C's house) and C and I will be living there. I paid for 20% and C is only paying for the remaining 10%. However, when it was time for payment, C became reluctant. Further, C's parents accused me of wanting money, calling me greedy and called my parents greedy too. C's brother called me a gold digger and said I only married his brother for the money. C's brother is feeding C lies and is trying to sabotage our marriage.

Worst of all, although this is C's and my house, C is only paying for 10%. C's parents have 5 properties and a lot more in stocks but I never asked anything from them. I'm being called a gold digger because they dont want their son to pay for his own house. C never defends me, he smiles and laughs when his brother talks to me like that.

I feel so trapped with C, I want to get out of this marriage but I didn't sign a prenup and feel stuck.
