Met his other sister today…?

Anonymous
So my boyfriend invited me over to a family function and I met his sister for the first time. His sister and I had a conversation and she mentioned to me how her brother (my boyfriend) always told her since 10 years ago that he doesn’t want to get married and I told her that he told me otherwise. He brother told me that he wants to marry me one day and that he told me he never really saw himself getting married in his past but now he does. His sister also told me that if he didn’t want to get married 10 years ago, why would he change his mind now?
I didn’t bring this convo up to my boyfriend because I believe my boyfriend. What do you guys think?

He’s the first guy that literally treat me like a princess. His communication is great. He always tells me how he sees me as his wife and that he feels we will get married sooner that ever. I see this long term he knows my family and they love him. His family, especially his mom likes me too
