SD doesn't brush her teeth
Over the weekend Step-daughter was at our home. On Saturday Step-daughter was doing her homework in the kitchen with her cousin(who is my cousin also), who slept over. I came downstairs with fiance. I went to the kitchen, and I asked if step-daughter and my cousin had brushed their teeth? My cousin stood quiet because, the day before he had told me he had forgotten his toothbrush. Step-daughter replied,"no." I waited a few minutes to see if step-daughter went upstairs to the bathroom to brush her teeth. Step-daughter continued doing her homework. I then told my cousin to go upstairs and brush his teeth, I gave him a toothbrush. When my cousin walked away, I told step-daughter that when my cousin returns she should go to brush her teeth.
My cousin came down and step-daughter went upstairs. A few seconds later step-daughter came back inquiring which one was her brush? Fiance, step-daughter's dad is sitting in the living room, and he goes what do you mean which one is your brush? Step-daughter says they are two red toothbrushes. Fiance is like bring down the toothbrush holder. Step-daughter finally figures out which one is her toothbrush, and returns upstairs to brush her teeth.
When step-daughter returns I am cleaning a bottle in the kitchen. I proceed to ask step-daughter has she been brushing her teeth? Step-daughter states,"yes." I then ask step-daughter if she brushes her teeth every weekend she is here how come don't you know which one was your toothbrush? Step-daughter replied that there were two toothbrushes and she couldn't tell which one is hers. Fiance interrupts the conversation, and is like what are you getting at? I then tell him why are you interrupting me? Fiance is like because, I want to know where you are headed with this. Now I tell fiance you just told your daughter I can't question her. He is like no I didn't. I am like if you are questioning me that is the message you sent to step-daughter that I can't question her. I am like especially when I pay mortgage and bills here. Fiance then says I was just questioning where you were headed with the questions. I am like if she is washing her teeth it doesn't matter how many toothbrushes are in the toothbrush holder you would know which ones is yours. This leads me to believe she isn't brushing her teeth. I told Fiance to end the conversation.
Fiance then emails me to apologize but, I replied since he did what he did I will never question to direct step-daughter to do something.
My question to anyone was I wrong or is fiance wrong? Please Advise.
