AITA for banning mentions of my son’s stepmother and stepsisters at his funeral?

My son was 17, and he tragically died in a car crash a week ago.<br><br>He was born with a genetic condition that impairs his visual and auditory abilities, as well as his intellectual functioning. He will always be a 4-6 year old boy in terms of understanding the world around him. He was also non-verbal. <br><br>He was a so sweet and so kind and he touched so many people’s hearts. <br><br>I am a single parent. His biological father is not in the picture. <br><br>My son had a stepfather, my husband, and stepsisters. My husband has twin girls from another marriage. The girls are 14 now. He has full custody of them as their mother is an addict and they have not been in touch for six years. <br><br>I have been married to my husband for nine years. We dated for two years before getting married. When we first met it was because our sons went to the same school for children with special needs. Our son’s became friends and we became friends as a result of that. We fell in love quickly. <br><br>I am top executive at a large charity, while my husband runs his own very successful business. We are very wealthy. <br><br>My stepdaughters have been very spoiled by their father. They were given everything they ever asked for growing up and rarely have had to deal with disappointment, as their father never wanted them to suffer in any way. They are very top or middle middle class. My daughter in law is very sweet, lovely and caring. My stepdaughters are more challenging. They have never liked my son very much. They found his disability offensive, and have been making fun of him since they were little. I have spoken to my husband so many times about this, and while he admits this is wrong, he still defends them. He has never punished them for their behavior. In fact, the three of them are a closed club, and I have always been automatically left out. <br><br>Their behavior became worse once they turned 11-12. My son is big and he is strong, as part of his condition. He can not control his strength, and he has damaged property several times, including their things. They have held grudges for years, and have been vengeance on him. As an example, they would put their phones on the floor, and then cry to their father because he destroyed them. The punishment for my sons was always harsh, while the girls have never been punished at all. In fact, they were bought new phones as presents. <br><br>Their hatred for my son was so bad and I have asked my husband for us to live sperately so many times. He has always said no. In return, he has asked for us to institutionalize our son. Which I have never agreed to. <br><br>The hatred has not stopped after my son’s death. In fact, it has become worse, as my son can no longer defend himself. My stepdaughters have been celebrating his death, as well calling him the most horrible names. They have also been calling me the most horrible names and treating me very badly. My husband is allowing this. He has not defended me or my son. In fact, he has said that I brought this to myself. He has also said that I should be grateful towards him and his daughters for accepting my son and that I should be grateful that he has taken care of me, as otherwise I would have been left alone and become a burden. <br><br>His words really hurt me. <br><br>Anyways, my son’s funeral is next week and I have been planning it. My husband and I have been discussing details and somehow my stepdaughters and his mentions have come up. He has asked me to talk about them. I have said no. I asked him to talk about them at their mother’s funeral. <br><br>This has caused a huge fight. He has called me a horrible and immature person who is letting her emotions cloud her judgement. I have called him an asshole. <br><br>I am not going to change my mind. My son’s funeral is not the place to talk about them.
