He has a lot of money while his mom is in poverty

I've been seeing this guy for 3 months and honestly he seems perfect. He's hilarious and I like funny guys. Down to earth. Extremely ambitious. He's also a very wealthy person. He's a private chef now but has been a head chef. Has an actual degree in culinary arts and hospitality which I didn't know where degrees. He also makes money off of YouTube and tiktok for his cooking videos AND he's released two cookbooks. So over the years he's become pretty wealthy and owns a huge home. I received the most bizarre text from someone who after piecing together things with research seems to be his sister. She said "Glad my brother is finding happiness. Maybe you can convince him to care about his family. Especially his own mother who's living in her car while she's so deep in poverty while he lives it up in a big house."

I found his mother on Facebook and it's true she's living in a car. He's never really talked about his family. I've asked before and he says I need to get him drunk if he's going to talk about that. I don't know if I should ask because when I think, I can't imagine myself living in a huge house making so much money while my mom is living in a car and in poverty. And my mom wasn't even the best mom. She did do her best with what she had though and made mistakes. She wasn't perfect. Would it be weird to ask?
