So me and my ex roommate are both 19. We were roommates last fall but she dropped out shortly after we first started school. She was hanging around some people she shouldn’t have and was doing drugs (cocaine) and got pregnant but had an abortion. Her mom said that she went to rehab the early part of this year and was doing good but recently told my mom that my roommate started using meth. I was on Snapchat and saw that she was selling ecstasy. I was wondering if I should let her mom know so they can get her help or if I should just mind my own business.
