Confused

I’m a newly wed. We got married in September 1st, September 15 my MIL went into the hospital, November 2nd my husbands grandmother passed away then on the 5th , 2 days later, his mom passed away, since then it has been a struggle we are currently living with his dad and older sister (Down syndrome) to help with everything. But it’s constant criticizing, I have heard his family say so much stuff about my husband and I during the funeral. Yelled at me because apparently his mother wasn’t my mom, my mom is still alive she was my mother in law and I have no right, saying shit about my husband is living off of the dad... even my husbands younger brother told me my husband is a lier and he’s manipulative. That’s why he got everything he wanted. FYI my husband has struggled and he made it he worked his ass off to be where he is. His mom was his rock and she was always there to support us, family is the most important thing for my husband. And my MIL was like my best friend she was always there for me and I loved her like my own mother, it hurts me so much to hear this and we are still recovering for all the financial issues with the wedding and then 2 funerals .. how can I tell my husband about his family without marking me look like I’m the one causing a problem.. it hurts so much and I don’t know what to do.
