I joined the new startup of my sister's boyfriend. He previously founded and was CTO of one of the top 50 biggest tech companies. I now never speak to him or my sister anymore. Only fights and blocked social media accounts and have given up ever seeing my sister again. So at least for family: Don't do it. It's not that big of a problem to never see a specific friend again but they have driven me out of my mom's side of the family, I can never see my sister again. Not worth it.
