My sister-in-law claims I’m scamming her with cryptocurrency investment invite

I am a 40-year-old divorcee, living with my 12-year-old daughter in a house adjacent to my mother’s, where my younger brother’s wife also resides. Despite our separate living arrangements, I join them for dinner each evening at my mother’s house. My sister-in-law and I frequently clash due to our differing views.

I adhere to a philosophy of self-cultivation, advocating for the treatment of minor illnesses through breathing exercises and physical activities, avoiding medication which I believe to be costly and harmful. This contrasts sharply with my sister-in-law’s approach, as she insists on medication for every ailment, no matter how minor, and is vocal in her disagreements with me. She often argues that if everyone adopted my views, pharmacies and hospitals would become obsolete, and she expresses these opinions disrespectfully.

Our disagreements extend beyond health matters. I have advised my mother on investing in cryptocurrency, and although profits have not yet materialized, continued investment is necessary.

When I extend the same suggestion to my sister-in-law, she dismisses it as a scam. I told her that if she didn’t partake in the investment, she should not expect any future profits, to which she retorted that I was living in a fantasy world and wrongly pushed my philosophy of self-cultivation on others.

Furthermore, my sister-in-law, who is unemployed and reliant on the money her husband sends, only performs household chores for my mother and does so without much care. I believe it would be better for her family to move out and live independently, though my mother disagrees.

What should I do with her?
