Frustrated with in laws

I have been with my fiancé for 5 years now we live in a different state then my in laws both of our sisters are full of drama. My brother in law just recently started seeing a new girl who automatically thinks that she’s gonna be forever. Which I’m not a fan of her already in 5 months of them dating as she’s made some very uncalled for “jokes” about introducing my fiancé to her sisters and etc. But now my sister in laws both of them say they want to move closer to us. I just don’t know if I can handle all the craziness. I love my in laws but they are a lot to handle. And I don’t know all the stuff happening down where they live daily so when drama hits my sister in law likes to tell my fiancé that she just can’t handle this or that. I love our nieces and nephews but I feel like my in laws don’t live in the real world. My fiancé still pays their car insurance and phone bills every month along with we have lent them thousands of dollars. Just needed to vent
