OP, my advice to you is go with your heart. Move out, don't live with your parents. and they will have NO control over you.
May I ask, why they disapprove your boyfriend OP? Are you guys Interracial couple?

My mother disapprove my husband because he is not Chinese.
Trust me, I know how you feel. All hell broke lose too when I told my Chinese mother that I'm dating my then boyfriend, now husband (he's Black)

Let me tell you my situation, your not the only one with parents disapproval.
I'm a Financial independent girl. I live on my own for more than a decade without a penny help from my parents, yet my mother still try to control who I date.

I'm 30, and I recently married my boyfriend who is 29
Our whole relationship, my mother didn't approve because I'm Chinese and he is African.
We got married anyways at a simple Courthouse ceremony, with 2 witness: my husband mother and my older brother.

My Chinese mother refused to give me her blessing. Both of my parents didn't show up at the Courthouse, but we still got married! Yah!
He is an awesome husband, he adores this Chinese wife of his. I have no regrets this lifetime.

btw, my mother disown me. Heck, I don't even live with her. It been 12 years since I walk out of her house. And she still trying to control who I date/married just because she is mommy, go figure.

Being Chinese and disown my your parents that is very hurtful, I feel a part of me is missing. The day before the Courthouse ceremony; I phone my mother in desperation that she would show up, and give me her blessing. But Nope, she still belittle me and insult me for married him
I cried after I hang up the phone. But I told myself to stop, because last thing I want is my husband who work 12-14 hours shift everyday to come home and see my crying eyes.

Good luck to you OP, follow your heart.
