My husband threatens divorce unless I let his nephew and niece live with us

Currently expecting our first child, my husband and I reside in a modestly sized apartment of approximately 70 square meters along with his nephew and niece, who are both in their mid-twenties. Their presence and differing lifestyles have made it challenging for me to feel at home, compounded by the limited space we must share.

I broached the topic with my husband, suggesting that once our baby arrives, it might be time for his nephew and niece to use their stable incomes to support themselves independently.

In response to my proposal, my husband adamantly refused, even going so far as to threaten divorce should I persist in wanting them to move out. This situation leaves me in distress daily, leading to many tearful nights and deep contemplation.

Should I go to my mother’s house to stay for the rest of my pregnancy? Please give me some advice.
