So I f23 has been dating my boyfriend who's m49 for about 4 years now. About a month ago I finally met his daughter who is f31f after I was holding it off for years. His daughter knew since the beginning that we were dating but we haven't met because I knew that some people have different opinions when it comes to me and my boyfriend's ages. Anyway, a month ago I and my boyfriend invited her and her husband to dinner. When they arrived my boyfriend went out to grab some drinks from the store so I was the only one home. As soon as she saw me answer the door she curled her lip. I'm 5'2 and she was about 5'11 she was kind of looking down at me. I guess she didn't expect me to be short or look the way I did? From the face, she gave me I knew this was gonna be interesting. I kept trying to start a conversation with her but her husband was the only one who answered until her father came back home. My boyfriend finished helping me with the cooking and we all sat around the table, prayed, and then ate. While we were eating me and my boyfriend were holding hands and he was complementing the food I made and then suddenly his daughter raised her voice asking us not to show affection around her. We didn't wanna make her uncomfortable so we just kept our hands to ourselves and finished eating. My boyfriend went into the kitchen to put the plates away and grab dessert and his daughter followed him. I could hear from the kitchen that she was yelling at him about dating someone younger than her and that she was grossed out by it. She also said I was a literal child but I'm 23? My boyfriend started yelling back that he loved me and it wasn't her place to say anything. They left and he blocked her right after. It honestly hurt my feelings but like I said everyone has their own opinions. So Reddit aita?
