My parents repeatedly insult and degrade my husband to a point that they personally attack him on issues such as how much money he makes, how he dresses, etc. They have been doing this for many years until a little while ago, they burst at him and crossed every line of disrespect. My husband lost his temper and responded that they are doing wrong and he does not wish to keep a further relationship with them because of the way they wrong him EVERY time we meet (at gatherings, etc).
My parents at that time did the same with me and told me that i am blinded and that my husband is a liar, and so is his family, etc etc. My husband was selected by my parents, we had gotten married with everyone's consent and he is making a halal earning Alhumdullilah. My parents also gave me the ultimatum that I have hurt them over the years by siding with my husband. At this point, my siblings are also siding with my parents and all parties are at a no-talking relationship. I do not know how to proceed but am completely aware of the fact that my parents are in the wrong, as much as I hate to say it.
Islamically, how should a woman deal with such a conflict between her two families (i.e. between her husband and her parents), especially insofar as she is expected to maintain ties with both?
