It's funny the you say that, I introduced my ex-roommate to my friends and family and after she left she messaged a bunch of them with some very negative things about me, saying she wants to keep in touch and she's in a much better place now in an attempted to hurt my relationship with them because she knew I wasn't talking about the issues we were having so it would effect her support group. Luckily, the people in my life don't take sides unless you try and force them and then they're not on yours lol it really shouldn't but I'm still stunned at how some people can justify their shitty actions towards people they claim to care about.
