I'm not going to give my girlfriend my family members phone numbers
Why don't you want to give your girlfriend your familie's phone number?
She is trying to run a MLM scheme.
You shouldn't be involving yourself in this scheme in the first place. She is your girlfriend, tell her that this is not right to do.
Aren't you supposed to be helping me? I'm just not following through on my agreement.
What she is trying to do is not right. Scamming other people is bad and it is your responsibility to inform her of that.
