My brother and sister-in-law have been married for six years. I love them both dearly. They adopted a little girl about a year ago. My parents were happy about this too at first. They got really angry when my brother and sister-in-law announced that their daughter would be their only child and they did not want biological kids. My mother and dad lost their shit. They told my brother he had to get my sister-in-law pregnant. He was the family's male heir and he would have to have a biological son to carry forward the family name. This makes no sense to me nor my brother and sister-in-law. It's not as if we're a family of European royalty who gives a fuck about the family name in this day and age. Well, my parents do apparently. They've been berating my brother and guilt-tripping my sister-in-law, making her feel like she's taking something away from our family. On one occasion, they actually suggested that my brother leave my sister-in-law if she didn't want to get pregnant and have a son with another woman. What's even worse is that they've stopped paying attention to my niece. Earlier, they would call and talk to her almost every day, but since they were told about my brother and sister-in-law's decision, they decided to stop calling her. This pisses me off and deeply saddens my brother and sister-in-law. This child is young and doesn't deserve this kind of treatment. Yesterday, I called my brother. He seemed very upset. He told me that his mom and dad had called him and said they had talked about something unrelated. When he asked if they wanted to talk to their granddaughter, they said they'd talk to their real grandchild when my brother came to a sentence and decided to give him one. I was angrier than I had been in a long time. I called my parents and unloaded on them. I told them how selfish and cool they were being and how dare they take out the anger on my niece. Along with a lot of other things I can't remember, my mom started crying as she's not used to being yelled at. I understand that yelling may be a bit much, but I just can't believe how also selfish they're being towards the kids. So am I the asshole or are they?
