I, (28f), have a younger sister, Amy (24f). We've always gotten along very well and are very close. Our parents worked a lot when we were little. But we still had a good childhood and never lacked for anything. When I left home and went to college, she was the only one I had contact with the most, and she visited the house often.

We both grew up, always close to each other. Now I'm pregnant with my second child. My first child is 2 years old, and Amy has been the best aunt ever since he arrived. She's also helped me a lot, especially now that my husband has been working longer hours so we can save as much as possible before the second baby arrives. This one wasn't planned like the first, but that doesn't change anything. We're still very happy to be growing as a family.

But on Wednesday, the day of the family dinner, I arrived a little early and spent some time talking with my sister. The topic of marriage came up. I asked her if she was thinking about getting married to her current boyfriend (with whom she's been for four years). She surprised me by telling me she was thinking about breaking up with him because things weren't working out anymore. I won't deny that I'm happy about it; I never liked my sister's boyfriend. He seemed too stingy and sensitive; I didn't see him as a good male figure, one who would protect and provide for my sister. I tried to distract her so she wouldn't feel guilty by mentioning the advantages of being single again.

Everything was fine until I mentioned that I would find a good man with whom I could start a family, and she reminded me she was childfree. The only time she said that was after her ex had assured them, for both of them, that they didn't want children, but I didn't think she meant it; I thought she had only agreed to be one for her ex. But she didn't have to do it if she didn't want to; she didn't have to pretend. But this bothered her and reaffirmed that she didn't want children. I got angry, reminding her that she said many times she wanted a family until she started dating her idiot boyfriend, who brainwashed her. I never spoke about her relationship before, but I think if she's going to break up with him, she shouldn't let his selfish opinions stay with her. Or maybe what she wanted was to be alone for the rest of her life? My sister didn't answer me and left me talking to myself, and then during dinner, she didn't speak to me again. I decided to give her space that day, but now, two days later, I've continued to text her, and she hasn't answered.

Every time I think about the subject, I feel angrier. I'm afraid she'll be left alone, without a family of her own, who will always be there for her. If it were anyone else, I wouldn't care, but I don't know how to talk to her so she'll realize it. And although she hasn't spoken to me, my mom is angry about what I said to Amy and that I should apologize, even though I know Amy's decision affects her a lot, too, because they've always taught us about family valious. So, I don't know why I should apologize; I'm genuinely concerned for Amy.
