Its so sad how many families are impacted negatively by MLMs.
I’m not sure this will be helpful but no one in my family said a word to me about my MLM. Even my husband supported me (though I found out later he had his doubts). It was my own questioning in the face of the reality that A) I wasn’t making a dime and B) I was spending a lot to not make a dime.
Maybe if you found a way to pose questions in a supportive way where the answers might spur some thinking?
