just need a few opinions

Kandi • Mom to 3 beautiful girls. Expecting august 2020

ok so my boyfriend son who is 19 fixin to be 20 moved in with us about a year ago. he doesnt go to school just has a part time job he lives here with us he doesnt have to pay any bills we gave him a car to drive and we pay the insurance on it also the only house chores he has is I ask him to do dishes once a week and he is supposed to take the garbage off since he is driving our suv. well he came home with a dog and it started growling at people running after them so I told him he had to get rid of it and it started war. he text his dad and told his dad if he had to get rid of her I needed to get rid of mine too. and then he started saying he was tired of doing stuff for me hes been keeping his mouth shut for a long time about it. that theres nothing wrong with me just that me and my 11 yr old daughter are lazy even though I make my 11 yr old do dishes many times a week and she helps do laundry. so he moved out. my boyfriend didnt take up for us and just kept telling his son he was sorry he didn't want him to leave. I ask him what all his son had said about me and my daughter and he was like nothing I was like I know he did. so now my boyfriend is pissed at me saying that's why he can't have a relationship is because everyone hates his son. I told him I didn't hate his son but he had it easy here no bills a free vehicle free food doing dishes once a week and hes not a child hes fixin to be 20 yrs old. do yall think I'm in the wrong for saying something? should I have just let it go. also I forgot to mention me and my boyfriend have a baby she will be 1 tomorrow so that's why I ask for him to do dishes once a week cuz it's hard doing everything yourself taking care of a baby. my bf works somedays 16hrs a day but when he is off he helps
