Parn, what made you think she needs to be alone for a while?
There is nothing wrong in knowing more people. As for
unnecessary trouble, she will have to learn how to deal with them
because trouble can come from anywhere, whether she likes it or
not....if she needs help, she can ask her friends or
colleagues...this is how you learn and grow.
Because I know it so. 
And I'm sure you're not the first person in her lives to notice
this about her, and you can be sure you won't be the last person
who will try to "save" her from her situation.
One good example, Not all sex workers required some form of
rescuing from guys like you.
Get it? Either you do or you don't. Don't disappoint me.
If you like her, make sure you MUST also learn to LIKE and ENJOY
her decision that she has chosen to make....especially decisions
such as this.
And if you can't respect that about her, then you be better off
dragging your presence far far away from her for her own good and
your own good too.
