What's wrong with your parents buying a house for my daughter to live in? You married my son, so what's yours is my family's.

I myself am the kind of person who doesn't fuss over things, the type with no scheming and fairly generous. But what I never expected was that my generosity and easygoing nature would, in the eyes of my in-laws, be taken as something I was simply obligated to do for their family, just my duty, not something that counted as any real contribution - and the moment I wanted to take it back, I'd face their unanimous accusations.

My husband's family circumstances weren't good. He came from a single-parent household; his father passed away early, and afterward my mother-in-law raised two children on her own salary alone. Under circumstances like that, it was only natural that the whole family had suffered quite a bit during all those years of financial strain. By the time I met him, the family's hardest times were already over, and on top of that he was fairly capable and doing well in his career, so my family didn't object much - they felt that although he couldn't yet be called very successful, his prospects for development were good, and they regarded him as a stock with potential.

Our family was comfortably off, and I hadn't suffered much since childhood. I myself simply didn't think that much about it - I just felt I liked him and wanted to be with him, that was all. Later, our marital home was also bought for me by my parents' family, while my in-laws, when we married, didn't even give much of a bride price - just a token gesture. Our family didn't ask for it either, and it was deposited together with the dowry money into an account under my name and brought over with me. Our family had already been quite gracious to go this far, yet my mother-in-law was still full of nitpicking and dissatisfaction toward me. She always felt I was delicate and spoiled, that I couldn't do housework, and that my husband indulged me too much - in short, she found fault with everything.

After we married, my mother-in-law moved in to live in the marital home my parents' family had bought for me. I thought she was an elder of the family and that this was only natural, so I didn't object. Besides that house, before the marriage my parents had also bought me a small studio apartment. After I married, my mother-in-law said that the place was just sitting empty anyway, and that it happened to be very close to where my sister-in-law worked, so why not let her live there. At the time I didn't think much about it and just let her move in. But as time went on, I discovered that the two of them, each living in a house bought by my parents' family, not only didn't give me a single cent for living expenses, but often asked me for money to buy things. My mother-in-law also spent all day finding fault with me in front of me, and my sister-in-law made a mess of my small apartment. Later I thought it over: there was no need for me to take responsibility for my sister-in-law - that was my mother-in-law's responsibility - so I wanted to rent out the studio apartment, which ended up upsetting my mother-in-law. She said to me directly in front of my husband: "What's wrong with your parents buying a house for my daughter to live in? You married my son, so what's yours is my family's."

After hearing that, I got angry too. My in-laws' family treated my contributions as a matter of course, believing that what was mine was theirs. But these are all my premarital assets, with no connection whatsoever to her family. Yet now even my husband is telling me to just let it go. I really can't swallow this, so tell me, everyone - what should I do?
